Vsfieldkit

- `vsfieldkit.prepare_nnedi3_chroma_upsampler` can now use the znedi3 or nnedi3cl plugin in addition to plain nnedi3 as before.
- Add compatibility with VapourSynth>=63 Python wrapper, broken due to renamed `PresetVideoFormat` enum. Thanks Mikewando.

Fix `vsfieldkit.resample_as_progressive`'s `avoid_chroma_shift` option. It was having an opposite effect from intended and resampling with even lossier shift.

The new method avoids the subsampling grid altogether by resampling the Cb and Cr planes separately, avoid unnecessary re-siting even with nearest-neighbor resampling.

New Features
Interlacing! Targeting deinterlacer testers and engineers in the broadcast space who’ve been instructed to avoid soft telecine. Two new functions:
* `vsfieldkit.telecine`
* `vsfieldkit.weave_fields`

[Re]sampling kernels to supplement the out of the box vapoursynth.resize functions, but specialized for vsfieldkit tasks. They can be found in the `vsfieldkit.kernels` module. Includes an nnedi3 kernel-maker for use as a chroma upsampler.

`vsfieldkit.annotate_bobbed_fields` for retro-actively adding a property to bobbed frames noting the field (top or bottom) they came from.

`vsfieldkit.output_frame_inferred_y4m` for outputting YUV4MPEG2 (y4m) data with metadata derived from the first frame’s properties, allowing for interlaced output, SAR, and chroma siting as available.

Changed APIs
`vsfieldkit.resample_as_progressive` kernel argument renamed to subsampling_kernel for clarity. upsampling_kernel argument added. It also now fakes luma-co-sited chroma during upsampling to avoid lossy chroma re-siting.

`vsfieldkit.resample_as_progressive` and `vsfieldkit.upsample_as_progressive` now default to Spline 36 for any chroma subsampling or upsampling using the new `vsfieldkit.kernels.resample_chroma_with_spline36`.

`vsfieldkit.upsample_as_progressive` now has upsample_horizontally argument. Defaults to `False`. `vsfieldkit.resample_as_progressive` uses this as `True` internally.

Contains updates to two existing functions.
`vsfieldkit.fill_analog_frame_ends`
* Allows overriding the pre-fill mode and gives better error messaging when the fillborders plugin is missing the requested mode. The default mode is now `"fillmargins"` instead of `"fixborders"` in order to work with the release version of fillborders.
* Works with progressive clips cropped by factors smaller than interlaced subsampling.
* More compatible with code autocompletion via removal of decorators.
`vsfieldkit.scan_interlaced`
* Can brighten newly-scanned fields via new ``attack_factor`` argument.

Allows [EdgeFixer](https://github.com/sekrit-twc/EdgeFixer) to be used for `vsfieldkit.fill_analog_frame_ends` instead of ContinuityFixer. Defaults to EdgeFixer if both are present.

* Adds `vsfieldkit.fill_analog_frame_ends` for cleaning up half-black lines at the edges of analog frames.
* `vsfieldkit.bob` now shifts to account for relative field position by default. Is deprecated in VapourSynth R58+

1.0.0 was yanked to immediately fix a `vsfieldkit.fill_analog_frame_ends` bug.
