Add PS4 system to info

[Deterous]

Adds PS4 as a supported system by redumper info Prints version and serial of the disc:

PS4 [track.iso]:
  version: 01.00
  serial: CUSA12345

More info: https://www.psdevwiki.com/ps4/Param.sfo

This is very similar to the PS3 SFO parsing, however the first sector of data in param.sfo is skipped. Additionally, PS4 discs do not have a SFB file.

Why is PS3 data altered by adding a dash (BLUS12345 gets altered into BLUS-12345), but PS4 isn't altered? (CUSA12345 stays as CUSA12345 instead of being altered into CUSA-12345).

This behavior feels inconsistently. Imho, you either alter all data, or none. Do not mix. As I stated in https://github.com/superg/redumper/issues/93#issuecomment-1793385805, I'm in favor of not modifying any data. But I'm fine with whatever path is taken, as long it's not mixed as it is right now.

@Ragowit , can you provide an example of PS4 disc where there is no dash in the serial? Do such discs exist?

[Ragowit]

@superg, on the physical PS3/PS4/PS5 disc they are always with a dash. But in the .sfo file, they are never with a dash.

EDIT: And on the spine, they are on separate lines, like: BLUS 12345

CUSA 12345

I'm confused then, I thought that SFO always has a dash. We should definitely standardize internal serial for all PlayStation consoles.

I popped in a PS3 disc now just to make sure I'm not saying wrong things.

PS3 discs have both a .sfb file, and a .sfo file. The .sfb file actually has the dash: BLES-01288 The .sfo does not: BLES01288

PS4 discs have only .sfo file. No dash: CUSA40400

Ok. let me get to the bottom of it and I'll bring it all to the common denominator.

Redump uses the internal serial from the SFB file for PS3 discs, which has a dash. There is good reason for preferring SFB over SFO (multi-game discs). PS4 and PS5 do not have an SFB. The serial in their SFO do not have a dash. I'm not aware of any PS3 disc that do not have a serial in their SFB file. And a PS3 disc without a SFB file is out-of-standard and not a real PS3 disc. The "altering" only occurs in the case where the serial does not exist in the SFB file (no known discs like this exist). In this case, the serial is taken from the SFO and a dash is added to be consistent with the rest of the PS3 set.
