codec: new functions osmo_{fr,efr}_sid_reset()
In Iec5c1f2619a82499f61cb3e5a7cd03ff0f020ad8 we added
osmo_{fr,efr}_sid_preen() functions that apply SID classification
of GSM 06.31/06.81 section 6.1.1 (osmo_{fr,efr}_sid_classify()),
reject invalid SID, and "rejuvenate" deemed-valid SID frames by
resetting their SID code word, correcting the one bit error that
may be present in a deemed-valid SID frame. However, the last
operation (rejuvenation of a SID frame by resetting its SID field)
should also be made available as its own function, as it may be
more efficient in some applications: for example, an application
may need to call osmo_{fr,efr}_sid_classify(), apply the rejuvenation
to valid SID, but also use the classification result to drive other
logic. Factor out these functions.
