If clear results is called from more than one task a race condition exists that may delete the same advertisedDevice twice.
This prevents this by swapping with an empty vector and testing for empty before freeing the resources.

* Adds a new enum class to specify the tx power type to set (unused by non-esp devices).
* When all type is specified it is now ensured that all the tx power types are set to the specified level.
* Correctly sets the power level advertised for extended advertising with legacy pdu selected.
The input and output report characteristics share the same UUID and the `getOutputReport` was returning the input report characteristic.
This change will return the correct characteristic by finding it with the index parameter.
When constructing a NimBLEAddress via string or other non `ble_addr_t` parameters it is important that the address type be specified.
This will help prevent issues where applications are not able to connect or identify scanned devices when comparing their addresses.
* General code cleanup.
* All functions that return a characteristic or service have been renamed to have a `get` prefix to better represent their function.
* All functions that set a value have been renamed with the prefix `set` to better represent their functionality.
* Added an `bool notify` parameter to `setBatteryLevel`, which if `true`, will send a notification of the value to the peer.
This allows the NimBLEServer instance to create a NimBLEClient instance to read/write form/to a connected peer.
Only one instance is supported subsequent calls will overwrite the previous client connection information and data.
