Add support for ignored nodes and returning a weight (#6)

- 4th detector coordinate set to -1 now means 'ignore this detector'
- Improve some of the decomposition logic
- Add
`chromobius.CompiledDecoder.predict_weighted_obs_flips_from_dets_bit_packed`
- Update some of the `gen` utilities for making test circuits
- Fix bit rotted CI configuration
