Piscola

This new release is a major update! The main change is the migration from george to tinygp, which is based on JAX. Apart from these, there are several improvements, although the overall 'spirit' of PISCOLA is the same as always, i.e. light-curve fitting with Gaussian Process.

Major update! The whole package is re-written. Filters, light curves and SED template are now classes. Light curve fits now come from the fitting of the mangling surface. Added sBV to the light-curve parameters.

This version includes a couple of functions to export the results of the light-curve fits and the corrected, restframe light curves. I also made the `normalize_data()` function implicit --> `_normalize_data()`, i.e. it is not needed anymore, although I also left it for compatibility purposes.

I made some changes, speeding up the mangling function calculation (usually x2 or quicker). This might come with a slight trade-off of accuracy/uncertainties (< or ~0.01 mag in final values). Also, piscola now sets the type of the metadata (SN name, z, ra, dec) to avoid issues with SNe whose names are only numbers.

I made some changes to fix the CLI so now it works.

I have added CLI under the bin directory and also changed to start using pickle5.
