rtpdec: Interpret the different G726 names as bits_per_coded_sample
For the standardized 8 kHz sample rate, this works exactly the same. For nonstandard sample rates, the different predefined G726 names (G726-16, G726-24, G726-32, G726-40) are interpreted as an indication of the bits per coded sample, even though their actual bitrates aren't what the name specifies. This feels more sane than using free-form names for nonstandard sample rate/bitrate combinations, e.g like G726-22, G726-33 for 11025 Hz. Signed-off-by: Martin Storsjö <martin@martin.st>
