Dipcoatimage-finitedepth

Fixed

- `coatinglayer.sample_polyline()` now uses 1st-order B-spline. This allows sampling polylines with 2 or 3 vertices.

Changed

- Polyline sampling is now done by `coatinglayer.sample_polyline()`.

Removed

- `coatinglayer.acm()` and `coatinglayer.owp()` are replaced by their counterparts in [CurveSimilarities](https://pypi.org/project/curvesimilarities/) package.
- `coatinglayer.equidistant_interpolate()` is replaced by `coatinglayer.sample_polyline()`.

Added

- `CoatingLayerBase.valid()` is added.

Added

- `finitedepth analyzers` command is added.

Fixed

- The frame size of the video output is now determined by the analyzed frame instead of the source frame. This allows the output frame to be a different size from the source frame.
