add the gdrive/gee methods

Fix #16

The idea is to add the needed methods to easily deal with exportation using the Gdrive account of the user as a proxy between GEE and Local folders. here is a first batch of methods, let me know if some are missing.

I like this idea, what do you think if we create a GeeDrive (or similar) model object to deal with this kind of tasks? instead of separate scripts. We could then associate a view when it's needed or just use the model when we have other needs. This will be similar to the planetapi package. I could also help in this one if you don't mind.

Sounds reasonable to me. I've leave this one on stale for a while so if you want to PR/push things help yourself !

I just updated the service to access through SEPAL with latest versions... I haven't tested the other methods, still WIP.
