Add option store CRC codes in MFT of NTFS drives

NTFS formatted drives have area in MFT to store meta data, user defined - specifically in the ADS - additional data streams.
Need option for storing the CRC32 or CRC64 code for all files in the ADS.
This enables later confirmation of duplicate files between drives very quickly. ie compare file A on one drive to file B on other drive by just comparing their stored CRC codes - instead of needing to read very large files.
