added Monsgeek Support (Specifically Fun60Ultra TMR)

[n8ventures]

Hi! Since I own a Monsgeek Fun60Ultra TMR, might as well give it a shot to add support.
Now there's a bit of a additional setup to get it working:

1. I have to either open the web driver via https://web.monsgeek.com/ or the downloaded offline driver,
2. go to Configuration > Magnetic Switch Settings > Simulation >flip on Start Simulation.

This is what I've seen from this request: AnalogSense/universal-analog-plugin#25

here's a preview:

It would be great if you could send whatever report the driver sends to start/stop the reports.

Hi! forgive me, I'm quite new to this. I figured via input-report-logger that the keyboard exposed multiple HID interfaces (3 HIDDevice instances in WebHID). With a couple of trial and error, I found that 2 of those are important.

the first interface: usagePage: 12, usage: 1
sends out the input key stream.

the second interface: usagePage: 65535, usage: 2
appears to expose a vendor control channel, which allows me to toggle the simulation switch by sending these bytes via sendFeatureReport():

constbuf=newUint8Array(65);buf[0]=0x1b;buf[1]=on ? 0x01 : 0x00;buf[2]=on ? 0xe3 : 0xe4;awaitdev.sendFeatureReport(0,buf)

the bytes were retrieved via WireShark + USBPcap by toggling the simulation switch on and off and used the Data Fragment outputs.

I sent in a new commit which has the new changes.
