Add support for filesystem roms

[unblob](https://github.com/onekey-sec/unblob) project [supports](https://unblob.org/formats/) many file system ROMs- CRAMFS, ExtFS, FAT, JFFS2, NTFS, RomFS, SquashFS (v3, v4), SquashFS v4 Big Endian, UBI, UBIFS and YAFFS (1, 2). It would be nice to have support for these formats.
