Support for AVIF files

[frederichoule]

Currently, trying to upload an AVIF file gives that error:

heif: Invalid input: Unspecified: Bitstream not supported by this decoder (2.0)
    err: {
      "type": "Error",
      "message": "source: bad seek to 107621\nheif: Invalid input: Unspecified: Bitstream not supported by this decoder (2.0)",
      "stack":
          Error: source: bad seek to 107621
          heif: Invalid input: Unspecified: Bitstream not supported by this decoder (2.0)
    }

This is for S3 Storage. I haven't tested yet for local storage, but I think we should support uploading of most popular image formats.
