refactor SEPAL map

[12rambau]

Fix #422
Fix #456

Main

The main objectives of this PR are to remove all dependencies to geemap as the number of functionalities provided is growing out of control and we are not using 10% of them. Also I took the occasion to partially revamp everything that was in mapping

To test the new code, you can use the dataset I provide in the following GIST: https://gist.github.com/12rambau/852d82c3b2c53ceee4a05c0f4cf01d9a

detail

• no more dependencies to geemap (it goees a bit faster but nothing that sensible)
• split basemaps from the other (the have the base member to true) there are now display in a different section of the layer

• create a handy find_layermethod it accept every possible key: layer, layer_name, index. return None if nothing is found
• since we have find_layer I overwritten remove_layer to use the same parameter (index, layer, layer_name). raise an error if nothing is found
• remove_all long wanting (at least from me) method to remove all layer from the map (leaving the basemaps).
• extract the DrawControl from the SepalMap. it will be way easier to solve customize the drawControl object to manage edition (not natively set up) #386 from there
• clean the way we store layers (remove the typed list local_layerand ee_layer as they are useless
• clean and deprecated the unused methods, 4 of them should be fully removed in 3.0
• create the EELayer to store the original dataset used in the layers (mainly for the v_inspector)
• store the raster path in the LocaleTileLayer (same reasons)
• extract the v_inspector from SepalMap and revamped the whole thing (I think it's nicer, and it's able to read the 4 types of data)
• create a MapBtn that use the appropriate styling params to be responsive and nicely display on the map. as it's a vuetify element we can use icons from latest fas/mdi. I changed both the v_inspector and the fullscreen to use it. I'll handle the issue of the tooltip in another PR.
• get rid of the small dot that was appearing sometime on the Map

TODO

• use messages for the labels
• test everything
• add the new components to the documentation

conclusion

I don't want to add new things (tooltips, edit in drawcontrol, fullscreen bug) to this PR as it would make it way too big. I'm happy to receive feedbacks on the new component to correct them

Some of the libs start to be deprecating python 3.6 I think we'll drop the support starting from this PR

I've made some comments in SepalMap. I'll wait until the "max_zoom" error is fixed so I can test the map on live, and I will keep testing the new feats.

I just made a single comment but I'm approving the review. It looks really nice, great job prr!
