Store exploration dates on url

[danielfdsilva]

This PR achieves 2 things:

• store the dates info in the url for sharing purposes (contribute to [E & A] - Page status sharing #527)
• Ensure that items in the url do not override each other. Since URLSearchParams were being initialized every time, adding something new, removed the previous ones.

Add the following the the preview url to see this working. You should see a dataset being compared and, a date range and an AOI.

Noting that it is not sharing every map state (ex.projection), but it seems out of scope for this pr.
