This currently matches on the `hsqs` start sequence of an image file. Additionally, the newly introduced filetype is registered as the type of the squashfs_driver which allows, for example, to mount squashfs without the need to specify a type parameter. This changes enable booting a squashfs with the simple `boot` command pointing to the location (device) that holds the squashfs. Note that booting with blspec is limited as the current squashfs driver is not capable of handling symbolic links.
