ffcb325aea Remove getRawData() and getDataLength()
Previously getRawData() made an unnecessary copy of the remote characteristic value data in order to return a uint8_t*. The resources used for this was unjustified by the value it provided as templates to retrieve such data have been added. Also the application writer could cast the std::string result of readValue() and/or getValue() however they choose using the data() method on the container if desired.

getDataLength() is also an unnecessary function as the length can be retrieved by the returned std::string from readValue() and/or getValue() with the length() method.

99ad62cdd4 Add template casting to readValue and advertisement data (#52)
The value returned by reading a remote characteristic or by getting a notification for it is kept in the class instance of the NimBLERemoteCharacteristic. This value can be accessed as a std::string type using the getValue() function.

This adds templates to read the value in the type used by the peripheral. The same functionality is implemented for getting the manufacturer data or the service data of an advertised device.

10f544f80a Update remote characteristic value from a notification
* Add NimBLERemoteCharacteristic::getValue(time_t *timestamp = nullptr) to get the latest remote characteristic and (optionally) it's timestamp.

* Added a timestamp to NimBLEAdvertisedDevice for the moment a device was scanned

5667c97efe Add access to the adv type of remote device
Adds new method `uint8_t NimBLEAdvertisedDevice::getAdvType()`
to get the advertisement type of the found device.

c5c9423893 Remove automatic discovery in NimBLEClient::connect().
Instead of discovering the peripheral database on connection and consuming
the associated resources this will give the user more control over the
discovery operation.

* Adds void NimBLEClient::discoverAtrributes() for the user to discover all
the peripheral attributes as a replacement for the former functionality.

* getServices(), getCharacteristics(), getDescriptors() now take an
optional bool parameter (default false).
If true it will clear the respective vector and retrieve all the respective
attributes from the peripheral. If false it will retrieve the attributes
only if the vector is empty, otherwise the vector is returned with the
currently stored attributes.

* getService(NimBLEUUID), getCharacteristic(NimBLEUUID), getDescriptor(NimBLEUUID)
will now check the respective vectors for the attribute object and, if not
found, will retrieve (only) the specified attribute from the peripheral.

10e50a8791 Add iterators to client remote attributes.
Add iterators for NimBLEScan: NimBLEadvertisedDevice, NimBLEClient: NimBLERemoteService, NimBLERemoteService: NimBLERemoteCharacteristic and NimBLERemoteCharacteristic: NimBLERemoteDescriptor

This is handy e.g. for showing every address of the advertised devices from a scan. To do so, first get a new scan and next:
```
for(auto pAdvertisedDevice: pBLEScan->getResults()) {
  Serial.printf("Address is %s\n", std::string(pAdvertisedDevice->getAddress()).c_str());
}
```
Of course any other property of the advertised device can be shown (or looked up, if that is your use case)

Also this is handy e.g. for showing every UUID in a peripheral. To do so, first connect to a peripheral and next:
```
for(auto pService: *pClient) {
  Serial.printf("Service UUID is %s\n", std::string(pService->getUUID()).c_str());
  for(auto pCharacteristic: *pService) {
    Serial.printf("Characteristic UUID is %s\n", std::string(pCharacteristic->getUUID()).c_str());
    for(auto pDescriptor: *pCharacteristic) {
      Serial.printf("Descriptor UUID is %s\n", std::string(pDescriptor->getUUID()).c_str());
    }
  }
}
```
Again of course any other property can be shown, or looked up.

6f4ee4b498 Breaking: Use std::vector instead of std::map in client classes (#46)
* Exchange map for vector, saving 1,076 bytes of program memory and 5,024 bytes of heap for a small device (LYWSD03MMC)

* Removing m_characteristicMapByHandle (using the handles form m_characteristicVector instead) saving in total (compared to the current master) 1,508 bytes of program memory and 6,500 bytes of heap for a small device (LYWSD03MMC)

* Change NimBLEScan container from std::map to std::vector

* Add function to get advertised device by address

* Update documentation

fc1022a46d Add new getServer() method.
Previously we used createServer() to get a reference to the server instance.
This was problematic when using advertising only as it would create a server
when starting advertising. This prevents that and provides better semantics.

03cb7b21d9 Conditionally compile code for specific roles.
This allows NimBLE options in menuconfig to reduce code size based on
the roles selected (scan/advertising/central/peripheral).

Significant code space can be saved by removing unnecessary roles for the application.
