[feature] Directives

[Vurv78]

Is your feature request related to a problem? Please describe.
There's no way to change the model/name/author etc of the chip

Describe the solution you'd like
I'd prefer one that doesn't break typescript in editors with a new syntax. So it could look like this:

/*
	@name Vurv
	@model xyz.mdl
	@author Vurv
*/

Describe alternatives you've considered
Using @directive syntax, just as E3 and E2 did. This would break using Expressive outside of the in-game editor, and be another thing straying further from TS, which this shouldn't do.

Also, this could lead into doc comments for any item, when the parsing for this is ready. That would be a different issue though.
