Add support for VEC Footpedal

[peternewman]

Is this a feature relevant to companion itself, and not a module?

• I believe this to be a feature for companion, not a module

Is there an existing issue for this?

• I have searched the existing issues

Describe the feature

Add support for VEC footpedal https://veccorp.com/foot-controls.html

I did a PR to add it to the xkeys module Companion is already using (so no code changes required to Companion), but unfortunately that's been rejected:
SuperFlyTV/xkeys#89

So I can either do as they suggest and make a library based on xkeys (not-xkeys?) by stripping out most stuff apart from my PR from a fork of their repo:
SuperFlyTV/xkeys#89 (comment)

Or something a lot simpler/lightweight like https://www.npmjs.com/package/shuttle-control-usb

Any particular preference there?

Usecases

Let people with VEC Footpedals use Companion in the same way as xkey footpedal owners can already.
