BLE works on Windows, hard code report id to 5

[davidqge]

Here are the hacks that make my RMK BLE keyboard connect to Vial through BLE on Windows.

Share this in case others find useful.

Someone with more python knowledge might able to get report id from Windows instead of hard code this.

hello, thanks for your PR. I started looking into RMK and noticed here: HaoboGu/rmk#77 (comment)

Note: This PR is actually a temporary solution only for Windows. To achieve general vial-over-BLE, the BLE vial service should be a customized service(not HID!). This is because Apple devices don't expose BLE-HID services at all. So, a host tool(like a wireless version of via/vial) needs to be implemented finally.

Given that comment, I think it would be better to wait for the final implementation from RMK side and then decide if it's something we should add to Vial. While I think BLE support would be awesome in vial, the value of adding this temporary BLE-HID solution (assuming that RMK later switches away from it) isn't very clear.

let me know any thoughts
