- Added a new parameter to `LoRaMacEventFlags` structure that indicates if there is applicative data on the received payload
- Corrected ADR MAC command behavior
- DutyCycle enforcement implementation (EU868 PHY only)
**REMARK 1** *The regulatory duty cycle enforcement is enabled by default which means that for lower data rates the
node may not transmit a new frame as quickly as requested
The formula used to compute the node idle time is*
Toff = TimeOnAir / DutyCycle - TxTimeOnAir
*Example:*
*A device just transmitted a 0.5 s long frame on one default channel
This channel is in a sub-band allowing 1% duty-cycle. Therefore this whole sub-band (868 MHz - 868.6 MHz) will be
unavailable for 49.5 s.*

function with false parameter.*
