Implement Forensic Image Properties

[pjrinaldi]

need to implement forensic image properties where applicable. EWF has properties, AFF4 has properties, wfi has properties, what else has properties for forensic images?

[pjrinaldi]

handling no crashes or hangs when the forensic image properties don't exist. need to build them, but want some time to think on them.

[pjrinaldi]

making progress on how to handle forensic image properties. just need to get properties, right them to the file and then read them back.

[pjrinaldi]

making progress on ewf properties. just need to pull them all in and then write them to a string so i can then write them to a file. the loop properties fail, and it could be because the uint8_t id value has a trailing \0 or doesn't have a trailing \0, need to check the header file and see and then fix accordingly, since the manual "case_number" entry works.

[pjrinaldi]

properties implemented for ewf. it works. just need to implement other properties for the other forensic images.

vhd/vhdx is implemented, working on aff4 next.

[pjrinaldi]

qcow/qcow2 is working. aff4 is on hold, that is crazy, complex, and convaluted. vmdk is working. need a phdi test image to implement phdi.

need to implement wfi and sfs properties next.
