All STX files start with the 4 bytes header "RSY\0"

For ST files, it's quite complicated to determine if it's a valid image, 
we can have a look at the boot sector and check if size match the 
expected number of tracks/sectors/sides, but this is not error proof.

At least, I don't think Hatari can do more checks when using mime types 
that what we already do when using --disk-a option or using the UI to 
open a file.
