More precisely, compressed bitmaps (decoding) are supported for DL TBFs
only, since it is required to decode them DL Ack/Nack if the window size
is increased which makes sense with multiple PDCH.

The reason for not implementing them for UL TBF ACK yet was the fact
that we only support single slot only in that direction and that the
imposed restriction won't probably hurt in most cases. We can still send
URBB even if the window size were larger than 96, so there are only some
cases with long runs of NACKs and very few ACKs which might suffer from
a slightly increased latency.

-> UL TBF ACK handling
