- now explicitly depending on `simba`
- now using `simba/libm` feature. This should always provide users with
required implementations for `f32`/`f64`, while falling back to `std`
when possible, and using `libm`, if explicitly required (depend on
`simba/force_libm` feature to do that). kudos to `simba`!
- Now using `generic_array_storage` v0.1.1 (Conv trait drastically
changed).
- `FitModel::ParamCount` type now has a less strict type bound, allowing
use of `typenum::Const` and even `nalgebra::Const`, if you feel like
it.
- Removed `Params` argument from `ConstOptimizationProblem` and
`DynOptimizationProblem`.
