Feature request: checksum .md5 plus HH_MM in filename

[BleakleyMcD]

1. When creating whole file checksum, have av-spex create both a .txt version and a .md5 version simultaneously. (SI DAMS VFCU setup needs the .md5 to trigger pickup but the .txt version is able to be read in Mac "preview", which is handy.)
2. Current whole file checksum name: JPC_AV_xxxxx_yyyy_mm_dd_fixity.txt and would like to have JPC_AV_xxxxx_yyyy_mm_dd_HH_MM_fixity for both .txt and .md5

@eddycolloton also turn off creation of JPC_AV_xxxxx_report_csvs when not creating a report

Do you want the .md5 file for SI DAMS to be named:

1. JPC_AV_xxxxx_yyyy_mm_dd_HH_MM_fixity.md5
   or
2. JPC_AV_xxxxx_yyyy_mm_dd_HH_MM.md5

As of this commit, av-spex will output both JPC_AV_xxxxx_yyyy_mm_dd_HH_MM_fixity.txt and JPC_AV_xxxxx_yyyy_mm_dd_HH_MM_fixity.md5: d253864
Let me know if you want to drop the '_fixity' from the .md5.

The 'fixity check' (off in step1, on in step2) will look for md5 checksums in files that end in '_checksums.md5' or '_fixity.txt' and have date in either yyyy_mm_dd_HH_MM format or the 'legacy' yyyy_mm_dd format. Fixity check output is written to _qc_metadata folder with a similar naming convention: JPC_AV_xxxxxx_yyyy_mm_dd_HH_MM_fixity_check.txt
