Refactor

[cgarling]

1. Use IrrationalConstants.jl to simplify some expressions involving constants like sqrt(2).
2. Replace some uses of standard Vectors for StaticArrays.SVectors. This is not an obvious performance win everywhere but it does make many of our constructors non-allocating now.
3. Add precompilation workloads.
4. Use [extras] in main Project.toml to set test dependencies, rather than separate test/Project.toml.
5. Add more tests for supported operations.
