Add complementary methods to NimBLEAdvertising and NimBLEAdvertisementData
Previous to this NimBLEAdvertising did not have some functionality that was in NimBLEAdvertisementData. Also NimBLEAdvertisementData was missing functionality that exists in NimBLEAdvertising. This resolves that by adding the missing functions to both classes. Changed: NimBLEAdvertising: Transmission power is no longer advertised by default and can be added to the advertisement by calling ::addTxPower() Added: - NimBLEAdvertising::setName - NimBLEAdvertising::setManufacturerData - NimBLEAdvertising::setURI - NimBLEAdvertising::setServiceData - NimBLEAdvertising::addTxPower - NimBLEAdvertising::reset - NimBLEAdvertisementData::addTxPower - NimBLEAdvertisementData::setPreferredParams - NimBLEAdvertisementData::setURI
