AVIF ImageProvider registering

[Michael Strauß]

The error message of the exception that is thrown by `ImageStorage`
when attempting to load an unsupported image  type is: "No loader for
image data". If you're encountering a different exception, maybe it
originates from somewhere else.

That being said, you're right that OpenJFX doesn't care about file
extensions and only checks file signatures. For both HEIC and AVIF
files, that's "ftyp" followed by a `major_brand` identifier. Maybe
you're encountering files with different kinds of `major_brand`?

Note that image loaders are an implementation detail of OpenJFX and
not public API, which means that the classes could change at any time
without notice.
