Harald Welte c7c48718ba Get rid of [now] superfluous HexAdapter
With the introduction of using osmocom.construct.{Bytes,GreedyBytes}
in Change-Id I1c8df6350c68aa408ec96ff6cd1e405ceb1a4fbb we don't have a
need for wrapping each instance of Bytes or GreedyBytes into a
HexAdapter anymore.  The osmocom.construct.{Bytes,GreedyBytes} will
automatically perform the related hex-string-to-bytes conversion if
needed - and during printing we have osmocom.utils.JsonEncoder that
makes sure to convert any bytes type to a hex-string.
