* 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
