Soifunc

- remove functions that were previously deprecated
- fixes for compat with most recent dependency versions
- expose SAD parameters in SQTGMC
- fix some presets in SQTGMC, mainly use a not-stupid nnsize
- remove dependency on havsfunc

- Deprecate functions that have (basically) equivalent functionality with existing functions in the interest of reducing code duplication and people trying to run the exact same functions from multiple \*funcs
- Update existing functions with updated tooling that should both run faster and be more resistant to unintended user input
- Improve some typing and make the package overall a bit more Pythonic, as well as make it a tad more typesafe in certain scenarios
- More useful and informative exceptions
- Expand some functions with functionality that can be built on in the future (i.e. presets)

- Fix Descale again, I need a better way to test these things before I push them

- Add `downscale_only` param to `Descale` function
- Expose `DescaleMask` as a separate function

- Deprecate `ClipLimited`, use `std.Limiter` instead
- Add `Descale` function

- Fix bug where SQGTMC may throw an error
