Bart Louwers 599240033a Handle QuotaExceededError in StyleStore (#1253)
## Launch Checklist

<!-- Thanks for the PR! Feel free to add or remove items from the
checklist. -->

When localStorage is full you start getting a "QuotaExceededError".
RIght now Maputnik does not handle this situation gracefully, it just
fails loading the style with a non-descriptive error message.

This PR purges localStorage and tries again when this particular error
happens.

It still does not show a descriptive error message. If you try to load a
style that is larger than what localStorage can handle, it will still
fail with a non-descriptive error message.

Increased the size of `example-style.json` so that it causes a
QuotaExceededError when running the regression test (try it before and
after this PR).
