Work from my [final project](https://www.cs.cornell.edu/courses/cs6120/2020fa/blog/bril-algebraic-data-types/). Adds the following algebraic type extension features: - Support in `brili` and `bril-txt` - Support in the JS, OCaml, and Rust libraries - Type-checker `briltc`...

bezier-rs 0.4.0: `Bezier::euclidean_to_parametric` is imprecise, with a big discontinuity at 0.5

In the current released version of bezier-rs, 0.4.0, the logic for approximating `Bezier::euclidean_to_parametric` is wrong. Specifically [here](https://github.com/GraphiteEditor/Graphite/blob/7951c5b5878965d9c509c0506faf4dcfae0d70a8/libraries/bezier-rs/src/bezier/lookup.rs#L35): ```rust // If the curve is near either end, we need even fewer...
