[Feature Request] Let gearscript accept unit classes in addition to arsenal exports.

[Bubbus]

Is your feature request related to a problem? Please describe.
It could be easier to define enemy factions if able to use pre-existing unit classes from editor.
The underlying setUnitLoadout command already supports this: https://community.bistudio.com/wiki/setUnitLoadout

Describe the solution you'd like
An alternative syntax to CREATE_LOADOUT and ADD_VARIANT which accepts strings representing unit class names.

Why is this this best way to solve the problem?
Right now the same trick is possible by placing the unit down and exporting their loadout in ace arsenal. This would make the process quicker and retain the unit's inherent loadout randomisation.

I'll take a crack at this.
