find_wave_files method looks also for *.WAV files (i.e. with capital letters in extension)
This merge request adds the following features
- data_handling.data_handling.find_wave_files looks not only for files with extension
.wav
, but also.WAV
- conversion from byte literal to str in external.wavfile to avoid TypeError:
warnings.warn("Chunk " + chunk_id + " skipped", WavFileWarning)
TypeError: must be str, not bytes
Obs: Remember to update development log when merging
