gsm0503_tch_hr_decode2(): new function, emits TS101318 format

The original design of gsm0503_tch_hr_{en,de}code() functions contains
a mistake in that a pseudo-RFC5993 format was chosen for HR codec frame
input and output, instead of "pure" (agnostic to outer RTP encoding)
form of 14 bytes.  We would like to change this design so that we can
feed pure 14-byte HR codec frames to the channel coding function and
get such frames back from the channel decoding function - however,
we cannot break libosmocoding API for existing users.  In the decoding
direction, create a new function that emits TS 101 318 format, and
turn the legacy gsm0503_tch_hr_decode() API into a wrapper function
for backward compatibility.
