Added beta support for Bunny CDN as a storage provider.
Note that Bunny CDN doesn't support ACLs so it can't do signed URLs like other cloud storage providers, so it is not suitable for WooCommerce, EDD or anything else where you want to protect individual files.
You can protect directories though and any files in a specified directory will be signed. This is probably a moving target feature wise.
Also note that this works differently then Bunny's WordPress plugin. Bunny's plugin works via pull where Media Cloud is push (it uploads your media to Bunny CDN). Which way is better is up to you to decide, though you can't use Bunny's plugin in a dev environment or on a localhost during dev.
Added documentation for Bunny CDN
Fixed Migrate to Mux task.
Migrating media now migrates .webp and .avif files regardless of what plugin generated them.
