NeFS: Officialize minimum disk size into the specs.

HPFS: Start implementing it.
UPS: Check PTime, and decrementing it when it isn't our time yet, also added new Subsystem entries.
FSKit: Better documentation and provide 256U instead of only 256.
EBS: Fixed HPFS magic number, which wasn't correctly bound to 8 bytes.
BUILD: Fixed blob.json for epm.asm
