refactor(plotter, renderer): add proof-of-concept renderer

[mcous]

Overview

This PR almost completely rewrites the v5 plotter for much better test coverage and adds an experimental proof-of-concept for the layer renderer.

Highlights

This plotter and renderer are able to deal with a majority of the Gerber fixtures in @tracespace/fixtures

This is mostly an internal development milestone rather than anything user facing, but there's a couple helpful debugging / inspection tool in here: pnpm dev now serves an app with the parse tree, plot tree, and render of fixture gerbers

What's left after this PR?

• Tests (and rewrites) of rectangle stroke and macro plotting
• Board rendering
  • Outline plotting
• Figure out a testing strategy for the SVG renderer
  • Probably rewrite it
  • Maybe some automated visual regression tests?
• Layer plotting / rendering of:
  • Step-repeats
  • Multi-polarity files
• A bunch of CLI stuff
• A bunch of website stuff
• A bunch of docs stuff

Notes:

• Remove CLI and snapshot tests from this PR, to noisy, do later
• Add various missing tests called out by codecov
• Rework drill operation mode and modal interpolate mode in GraphicPlotter; it's too easy to trigger unintended behavior
