Major update to outliers functionalities.

Various bug fixes on plots.

Functionalities:
- Compute phase angles from Coherence
- Fix a bug in summary_plot() that overwrote user's parameters.

This release includes:

- New functionalities:

1. Continuous wavelet transform from Torrence and Compo for evenly-spaced timers
2. Cross-Wavelet and Coherence from cwt, including a new dashboard to display the results.
3. Various bug fixes to Series functionalities.
4. Changes to `Series.summary_plot`, which now requires a Scalogram and PSD to be pre-computed and passed to the function


- Architecture:

1. `ui.py` is split into various model for the main classes in Pyleoclim

- Continuous integration is set up through GitHub actions

Starting incorporating wavelet methods for evenly-spaced data. This is an intermediate release for autoTS
