* `image.show_image`: added `show_colorbar` and `colorbar_title` parameters
* `image.show_mask` added `title` parameter
* `compute_activation_map`: added `show` (for plotting, `True` by default), `inverted`, and `set_nan_for_inactive` parameters

Other Changes
* Ignore NaNs for `play_video()` and other functions
* Added support for Python 3.12
* Improved error handling for MultiRecorderImporter

**Full Changelog**: https://github.com/cardiacvision/optimap/compare/v0.1.3...v0.1.4

* Add minmal GUI to `om.play_video` `video.play/play2/playn`
* Fix `om.load_video()` when using a combination of `step` and `frames` parameters
