Support for other CoolerMaster CK5xx keyboards

[cscheib]

These keyboards all use the same SDK, so you'd only need to listen for more USB IDs. I'm not a Swift developer, otherwise I'd submit a PR.

I cracked open the code, changed the product_id (pid) to 0x009f:

func startHIDMonitoring() -> Bool { return hid.monitorEnumeration(vid: 0x2516, pid: 0x009f, usagePage: 0xFF00, usage: 0x00) }

and was able to get my CK530 working with this... so it's definitely possible. I just don't know how to monitor more than one USB ID!

Forked and showed my work in #3

Perfect! I will find some time to refactor the code to include your changes.
The code is based on the sniffed USB communication, so I'm glad to hear that it works also for 530 series.
Thanks!

• modified code to support multiple USB PIDs and enabled CK530 model.
• updated the root readme.md
  -- CK530 is enabled
  -- how to enable other models
• the intention is not to enable other CK models until there is a positive feedback from the given keyboard owner
  -- this application is based on the USB sniffed communication and does not do the same operations which the official Windows SDK does
  -- in other words, even the single SDK is officially provided for multiple CK models, there is no guarantee that it produces the same USB HID commands for all those CK models

@cscheib Thanks for letting me know that CK530 is compatible.
The new release was created.

@vookimedlo awesome, thanks!

Note that although it works not all keys light up.

• ESC, F2, F3, F11, F12, PRT SC,
• ~, 2, 0, =, INS
• TAB, Q, P, ], , PGDN
• H ;
• B . /
• Left CTL, Right Alt, Left arrow key

I don't have a CK530 keyboard, so I cannot do USB communication sniffs and see where those mentioned keys are encoded.

However, you can debug it without a USB sniffer on your side, by changing offsets in map below (by 3 - // R,G,B -> three bytes).
