* feat: support no_std
`metal` feature supports `no_std` in configuration `default-features = false, features = ["metal"]`.
Float calculation is done via `micromath` crate.
All previously available functionality remains under default `std` feature.
Some tweaking of `python` and `wasm` features was done to compile tests.
* feat: get rid of floats (#2)
* feat: remove conversion to f64, fix features
* chore: uncomment symbols_required checker, fmt
* revert: add cdylib target for python support
* fix: generalize crate type

This reduces the time spent in the fourth phase from ~6% of encoding
time to ~1%, according to perf, and improves overall throughput by 3-4%
on large symbol counts.
Previously we used column major ordering. Switch to row major to
optimize sequential access of rows which is much more common in the
first phase, and can also be used in the fourth phase
This improves performance by ~10% on large symbol counts
Optimize Phases 2-5 to avoid writes to the first i columns.
Additionally, use pre-computed ops from first phase to implement third &
fifth phases
This improves encoding performance by ~15%, especially on large symbol
counts
This should make it possible to use serde to serialize and deserialize
encoders/decoders while they are in use. This is makes it possible to
ship them between processes as needed.
