Lvsfunc

**Changelog**

* Update stubs
* Update docs


**New Additions:**
* `deinterlace.TIVTC_VFR`
- Wrapper for performing TFM and TDecimate on a clip that is supposed to be VFR, including generating a metrics/matches/timecodes txt file.
* `dehardsub.HardsubASS`
- Generate a mask using an ass script, such as for dehardubbing AoD with CR DE.
* `render.get_render_process`


**Updates:**
* Functions with progress bars
- Update progress method, running them will probably be faster now

* `clip_async_render`
- Add `progress` param: String to use for render progress display.
- Fix a bug where it tried to read timecode information from clips that didn't have any

**Changelog**

* Updated various error messages to use the correct function names
* Couple README updates, disclaimer about unstable API included
* Typing fixes in `util`
* Minor docstring corrections

**Updates:**
* `misc.ripe_row`:
- Rewrite. It now uses a `mask.BoundingBox` instead of `kagefunc.squaremask` and you can no longer wipe two separate rows/columns at once anymore.

* `replace_ranges`:
- Moved to `util` (still accessible through `misc` and `lvsfunc.rfs`, but the former will be deprecated at some point in the future)
- Allow for negative and nonetype inputs (for a more apt description, check the docstring)

* `scale_thresh`:
- Moved to `util` (still accessible through `misc`, but that will be deprecated at some point in the future)

* `nneedi3_clamp`:
- Fix bug where `strength` would not be used properly

* `bidehalo`:
- Import dehalo submodule in `__init__` (oops)
- Add `sigmaS_final` and `sigmaR_final` parameters. By default `sigmaS_final` will be 1/3rd of `sigmaS`, and `sigmaR_final` will be the same as `sigmaR`. For more information, consult the docstrings

**Changelog**

New Additions:
* Add named Bicubic kernels (BSpline, Hermite, Mitchell, Catrom, BicubicSharp, RobidouxSoft, Robidoux, RobidouxSharp)
* Add a keyframe generator (render.find_scene_changes)
- Outputs a list of scenechanges determined by wwxd, scxvid, frames only found by both, or frames found by either

Updates to functions:
* Update dehalo.bidehalo
- Remove masking, this is now up to the user to handle
- Fix bug where float clips would error because bilateral can't handle them
* Source
- Fix a bug where the improper Matrix params would be passed (int to str param instead of int param which would break clips if you used `ref`)

Will be doing proper releases now with changelogs.
