[WIP] github actions rust cache (#131)

* add cache ext

* shorten artifact name

* cache rust cargo home

see https://doc.rust-lang.org/cargo/guide/cargo-home.html#caching-the-cargo-home-in-ci

* star artifact, relative rust cache

* forgot to relative prod rust cache

* seriously need one step per cache dir?

* forgot to fix artifact name

* likely need different key for each cache

* globs don't yet work, hardcode for now

* add releaseFolder option

MacOS has deeper folder structure than the others

* missed closing quote

* fix ubuntu artifact path

* use cargo home for cache dir

* set cargo home env

* try relative path?

* scrap env, use matrix

* wish it wasn't so verbose

* tilde

* cache rust based on hashed cargo.lock
