Re-enable dynamic packet length
The nrf24l01 used on the boards is probably a counterfeit chip. It
cannot acknowledge received packets (probably a bit flip of the NO_ACK
bit described here:
https://ncrmnt.org/2015/03/13/how-do-i-cost-optimize-nrf24l01/ ) if the
dynamic packet length is disabled.

Generate an ID according to the dip switches
The ID is used as the last byte of the RX address. It is also sent as a
part of the data packet to allow assigning the sending station to a
packet.
