Release 2.2.0

+++ Added
- A `destroy` function is now available to properly get rid of the viewer, which is useful for single-page applications.
- A new component named `StandaloneMap` is available to show a coverage map of pictures and sequences, without full picture display. It can be controlled programatically.

+++ Changed
- Calls to API are now using STAC standard notation for IDs lists (`ids=bla` instead of `ids=["bla"]`). Old notation was based on GeoVisio API misunderstanding of STAC docs. This __breaks compatibility__ with GeoVisio API <= 2.1.4, but makes viewer compatible with any STAC-compliant API.
- A new button in player advanced settings allows to augment image brightness & contrast (_☀️_ button).
- Mini map/viewer is now responsive, with a size increasing based on screen size.
- Photo Sphere Viewer updated to 5.4.3.

+++ Fixed
- Invalid map bounding box received from API was preventing viewer from loading. Now, a warning is shown instead in web console.
