Coldtype

Fixed
- ability to set workarea in coldtype 2d panel (blender)
- memory bug in harfbuzz bounding box calculation by downgrading to <0.47

Changed
- refinements to Coldtype 2D panel in Blender for timeline workflow

Changed
- base dependencies for coldtype (i.e. coldtype installed without any extra) no longer support "extended" font formats (woff, ufo, etc.), though [viewer] extra does still provide support for these; mido requirement has also been moved out of base into viewer; the point of this is to reduce the complexity of a "minimal" coldtype installation (i.e. when embedded as a backend service in another python application or a Blender extension, e.g.)

Added
- better support for custom output with ct viewseq
- experimental support for `Theme` class to set multiple color styles from a single object
Fixed
- blender venv-inlining now look for a "src" directory if it exists (to match new pyproject.toml-enforced directory structure)

Added
- `set_709` on `animation.export`/`FFMPEGExport` (so you can use older `ffmpeg` releases to export animations)

Added
- `ViewerSoloFirst` and `ViewerSoloLast` shortcuts
Changed
- `VIEWER_SOLO` is now a config option, not a one-off cli arg in renderer
