Add gif support to supabase image transformations - or specify in docs that it is not supported.

[jonathanlal]

Currently if you try and transform a .gif file it will make the gif static (by using only the first frame). Which is the default behaviour of imgproxy.

  const {
    data,
  } = supabaseClient.storage.from('bucket').getPublicUrl(
    'someGifFile',
    {
      transform: {
        width: 100,
        height: 100,
      },
    },
  );

imgproxy does support transforming more than 1 frame in a gif file but requires changing an environment variable:

IMGPROXY_MAX_ANIMATION_FRAMES

Perhaps passing format: 'gif' in the transform options could allow for it?

If not it should be at least updated in the docs that gif files are not supported in image transformations. Since it shows misleading information:
https://supabase.com/docs/guides/storage/serving/image-transformations

Please implement this supabase staff, it's already supported by IMGPROXY is just requires passing the env to imgproxy

@jonathanlal
actually, i got it to work on the self-hosted

you can add this to your docker-compose.yml
IMGPROXY_MAX_ANIMATION_FRAMES: 120

it can't be set to 0 though.

We need IMGPROXY_MAX_ANIMATION_FRAMES with hosted supabase to be at least 150 frames or configurable.
