[suggestion] Expand $() functions abilities

[vespakoen]

Happy new year!

I was looking at cadquery (https://dcowden.github.io/cadquery/apireference.html#d-operations) and thought their API is quite nice, I'd like to suggest extending it's functionality to include things like fillet, dogbone and the drawing functions that remember the "current position", like moveTo, lineTo, lineH, lineV etc.

Here is my hacky attempt at it (only has some basics at the moment): https://github.com/makercam/makercam/blob/master/src/drawing.ts

Hey @vespakoen Happy new year to you! That is a pretty cool API. Would be cool to make it a standalone project outside of MakerCam so that it can be used in other projects.

@vespakoen some of these commands such as moveTo, lineTo etc. might be good for a new ChainBuilder class. But that idea would only be a subset of what your example contains.
