Support for Zipped .HDF files or Gzipped .HDZ files

[ztronzo]

This is a request to support single file GunZipped HDF files named as HDZ and multiple HDF files which can be stored under a ZIP compression. as example: hard_drive_1 = Path\TargetFile.ZIP#/HD1.HDF hard_drive_2 = Path\TargetFile.ZIP#/HD2.HDF

Theoretically it should work the same as with floppy ADZ files and ZIP files containing an ADF This is to allow only temporary read/write which would have all changes/writes to be discarded after close.
