osmo-bts-trx: perform error concealment for FR frames
When a bad voice frame is received, it is replaced by
a silence frame. This may cause unpleasant audio effects.
This change implements a functionality to craft a replacement
frame from the last known good frame using ECU implementation
from libosmocodec. At the moment, only FR is supported.
Depends: libosmocore I06a21f60db01bfe1c2b838f93866fad1d53fdcd1
