Wavelet inspect

[jthermiz]

Minor necessary fix:

• Store final resample rate for wavelet data (not intermediate one)

Minor optional edits:

• Renamed preprocess_folder to preprocess_folder.py
• Added error messages for preprocess_folder.py
• Changed a couple of defaults
• Updated doc strings for various functions

Hi @JesseLivezey can I go ahead and merge this?

[jthermiz]

Re removing .py, sounds good. I didn't realize that not including a .py is common practice for scripts like this.

@JesseLivezey Are you ok with me merging this PR?

@jthermiz this PR causes 1 test to fail and there were also some formatting problems. Can you make another PR to fix?

The post_resample_rate changes introduced a problem in the code when the phase is saved.

pytest -sv tests/test_pipeline.py::test_pipeline
# tests/test_pipeline.py::test_pipeline FAILED

            series = [elec_series_wvlt_amp]
            if not abs_only:
                if post_resample_rate is not None:
>                   raise ValueError('Wavelet phase should not be resampled.')
E                   ValueError: Wavelet phase should not be resampled.

You can probably set your editor to automatically remove these sorts of whitepsace
