Bugfix and new info cli

[ModernMAK]

Fix metadata being initialized via create_drive, but not by getinfo/setinfo.

The new Info CLI:

usage: relic sga info [-h] [-q] sga [log_file]

Dumps metadata packed into an SGA file.

positional arguments:
  sga          SGA File to inspect
  log_file     Optional file to write messages to, required if `-q/--quiet` is used

optional arguments:
  -h, --help   show this help message and exit
  -q, --quiet  When specified, SGA info is not printed to the console
