[Feature] PS2/OPL support

[binarygeek119]

Is your feature request related to a problem? Please describe.
no, just something that would be nicer to have.

Describe the solution you'd like
opl or open ps2 loader loads iso from a nas or network share.
it has a 32 character limit. meaning some of the name is cut off
it also doesnt require the SERIAL to be in the name but loads faster with them in the name.

SLUS_207.45.Shrek 2.iso
SLUS_206.85.Ape Escape 2.iso

it be nice if you could scan the iso for the SERIAL there are a few tools out there that do this very thing. the SERIAL then could be used on a list (which are out there as well) to find the full name.
Describe alternatives you've considered
the ability to skip over the SERIAL in the filename

SLUS_207.45.Shrek 2.iso
SLUS_206.85.Ape Escape 2.iso

becomes

Shrek 2.iso
Ape Escape 2.iso

Additional context
this sound only need to happen with ps2 games.
ps2 iso renamer: https://www.psx-place.com/resources/eziso-renamer-by-raydenx.700/
another ps2 renamer: http://www.psxrenzukoken.com/nk2/download/psx-renamer-1-7-database/
this also has a database file the could be used.

ive looked in to this a bit more
here is a link to a tool that does just that.

https://github.com/valters-tomsons/PS2-Game-Title-Finder

you will need this file aswell

I had some trouble parsing GameIndex.dbf into a format usable in python, so I translated it to JSON (minus the patches).

Matching serial number with filename should be simple enough.

just make sure to use the way OPL uses the codes.
SLUS_206.85
wordcode + _ + 3#'s + . + . + 2#'s
SLUS + _ + 206 + . + 85
only say this as your json uses SLES-55671.
you may be planning to do some converting in code.
