cvm-rs: version 0.2.0

- switch to napi-rs. this mostly affects only the backend side of things, but IMO napi-rs is better (also, way less boilerplate is needed compared to neon).

- jpeg encoding no longer clones the input buffer internally (or wraps it in a Mutex as well), thanks to napi-rs not sucking in this regard. this is *probably* a micro-optimization, but will make it easier to later on do parallel encoding of all rectangles

- guac encoding is weird. This is kind of a painpoint of napi-rs but it's bearable
