Added setGain for LNA Gain (#408)

Browse Source 
* Added setGain for LNA Gain

Added setGain for LNA Gain

* Update API.md

Added API for setGain

* Added example to use setGain

Just use setGain after LoRa.begin
// set maximum LNA for better RX sensitivity
// 0: ADC is used and LNA gain is not used.
// 1-6: ADC is not used and LNA gain is used.
LoRa.setGain(6);

* Fixed spacing only

To change tabs to spaces.

* Delete LoRaReceiverCallbackWithLNAGain.ino

To remove as unnecessary.

* To add example for setGain

To add example for setGain as an optional setting.

* Added setGain

To add setGain

* Fixed typo for AGC

Fixed typo for AGC

* Fixed comment for LoRa.setGain(6)

* Make comment for setGain simpler

Make comment for setGain simpler
