V0.3.0

[ManonMarchand]

Rewrite ipyaladin to be based on anywidget

The idea was to keep all existing functionalities. Some things were just easy to implement along the way:

Fixes #49

There is a new method add_moc that detects whether a MOC is a dictionnary, url or mocpy object.
The add_moc_from_URL and add_moc_from_dict still exist and work but throw a deprecation warning advising to switch to add_moc.

Fixes #38

One can now use any of the parameters here : https://cds-astro.github.io/aladin-lite/Catalog.Catalog.html

Example:

aladin.add_table(top5, color="darkseagreen", shape="cross", "sourceSize"=20)

Fixes #31

Anywidget takes care of the portability on different platforms. We should not have any issues with VSCode/Colab/Jupyter anymore 🤞
