bbacdbcc96 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.

43bf2f17e1 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.

9cf2d476b8 Add interface for changing ggwave's internal logging (#52) 
* ggwave : add interface for changing ggwave's internal logging

Using GGWave::setLogFile() it is now possible to change the log file
used internally by ggwave, or disable it all together.

* ggwave : add comments about thread-safety of setLogFile

62b71c3322 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.
