Small fix on BME280 Config & CC1101-TXPower Throttle (#1382)

* https://github.com/1technophile/OpenMQTTGateway/issues/1380
CC1101 TXPower selection

* Creates the possability the define SDA/SCL Pins correct through a compiler switch from the platformio.ini
Sample:
  '-DBME280_PIN_SDA=0'
  '-DBME280_PIN_SCL=2'
