Support detection of PDsid

[Kaninbjerget]

Hi

Thanks for the great Ultimate 64!
As I can understand currently 3 SID replacements are supported for auto detection and auto configuration (ARMSID, FPGASID, SwinSid Ultimate).
I'd like to request one more to be supported.

A new firmware, version 1.54, for the Public Domain SID (PDsid) has been released and it now also supports detection and configuration of mode (6581 respectively 8580).

That would be really nice if that would be implemented as we're more and more that love the PDsid and prefer it over the other supported alternatives. Well perhaps the FPGASID technically wins but it's unsure if it's produced again and for many it's also too expensive.

Hope it's something you'll look into.

Thanks!

PDsid. Firmware and info can be found under Files on it's product page:
https://uni64.com/shop/index.php?system=3&m=70&item_id=7536

API info:

`The PDsid API is very simple:

1. Detect a PDsid:
   Write 'P' to $D41D, 'D' to $D41E, Read 'S' from $D41E.

2. SID Mode Read:
   Write 'P' to $D41D, 'D' to $D41E, Read Mode from $D41F.

3. SID Mode Set:
   Write 'P' to $D41D, 'D' to $D41E, Write Mode (0=6581, 1=8580) to $D41F.

That's all`

There's more info in the files in the zip file :-)
