c-api : add toggleRxProtocol() ( #60 )

This function allows to enable/disable Rx protocols during the decoding
process. This is useful when the Tx/Rx protocol is known in advance.

ggwave : fix out-of-bounds access in ggwave_decode ( #53 )
...
Also, provide a memory-safe overload called ggwave_ndecode()
The overload takes an extra parameter that specifies the size of
the output buffer and thus limits the size of the Rx payload that can be
decoded and stored.

ggwave : resampling fixes
...
The old output resampling was bugged and produced cracking in the audio
when the output sampling rate was different from the base sampling rate.
Additionally, the decoding wasn't properly handling resampled input in all
cases.
