edge: Support EGPRS uplink Ack/Nack messages

This commit adds EGPRS UL Ack/Nack encoding based on the CSN1 code.

Note that the bitmap encoding is still broken and not easy to fix
with the CSN1 framework, especially w.r.t. the length field.
Therefore this implementation will be abandoned and replaced by a
bitvec based one.
