patterns: Added DFIR Patterns (#442)
* Added /DFIR/ with patterns Added /DFIR/ sub-directory. Contains modified versions of built-in patterns for semi-automated Disk/Volume/Filesystem parsing geared towards Digital Forensics. Originals in /fs/ should remain in tact for spot placement. * DFIR_README.md * DFIR_README.md * DFIR_README.md * DISK_PARSER.hexpat * DISK_PARSER.hexpat * FAT32.hexpat * exFAT.hexpat * README.md Added DFIR related hexpats to table. * README.md --------- Co-authored-by: Xtreme-Liberty <59177844+Xtreme-Liberty@users.noreply.github.com>
