Orcasound workflow PR

Functionally it's similar to the OOI workflow, however with a hardcoded data source folder for tests. Spectrogram creation is different from OOI as well. prints were replaced with proper logging (for OOI too). Orcasound Python script also has some inputs (input_dir, output and NFFT (spectrogram parameter). Some NFFT investigation [1, 2]. .ts to .wav conversion was done using ffmpeg-python.
- bug fixes: fix handling of very short files (corresponding issue upstream), fix redefinition of builtin function
OOIPy in OOI workflow PR

OOI workflow was rewritten to use OOIPy package. Instead of processing each raw file it now processes 5-minute time chunks. Spectrogram creation is now reused between OOI and Orcasound, works for mono and stereo audio.
OOI inputs PR

Added input arguments to OOI Python script (using argparse, similar to Orcasound) and to the workflow itself. Now it is possible to choose hydrophone node, start and end time, segment length (acquired audio is split into 5-minute length chunks by default), output directory and NFFT. This PR also added the first tests, for utility functions (spectrogram creation) and integration tests for OOI with downloading data.
- bug fixes: fix failing test for spectrograms
GitHub Action for OOI

Repository. Docker Action acquiring data from OOI, basically a replica of existing workflow, input arguments: node, start, end time, output directory. Example run.
