Some extra keys are being treated as steno keys

[JorWat25]

Describe the bug

When Plover is active on my laptop, the mute and volume down keys become W and A keys respectively. According one website, they are keys <181> and <182>.

To Reproduce

Steps to reproduce the behavior:

1. Activate Plover
2. Press the mute or volume down keys
3. See W or A

Expected behavior

Either nothing should happen, or the keys should do their usual function.

Operating system

• OS: Windows 10
• Plover Version 4.0.0.dev9

Hardware

The laptop is an Lenovo Ideapad.

I should note it is only the laptop keys that do this. An external keyboard, also with volume keys apparently with the same code numbers, works normally when Plover is activated.

[user202729]

Plover reads scan code rather than virtual key code (vkCode).

I don't know what was the purpose (does it make a difference with Dvorak keyboards? Or something else?), given that Plover also use vkCode to determine if a key is a modifier key (PASSTHROUGH_KEYS).

A possible fix is: (moved to pull request)

This fix has the side effect that the / and Return keys on the number pad will not be mappable with this change. (not tested)

Or is it better to use vkCode for both?

I have the exact same problem on a 💻Dell Latitude E6410: volume down is a, volume up does nothing, mute is with, volume down+mute is was. Those three buttons' normal behaviour is blocked while plover is enabled; the volume doesn't change. These are the buttons autohotkey sees pressed when plover is disabled and I press down up mute.
