Bump version to 0.3.1

Changes since 0.3.0:

New Features

- Added `Branches` and `Dup` components that generalize `Parallel`
- Added predicate-based termination criterion in `Loop`, enabling
  run-to-energy mode
- Even lazier auto embedding QPU sampler
- Added parallel tempering workflow examples
- Importable workflows for `Kerberos`, `ParallelTempering` and
  `SimplifiedQbsolv`

Fixes

- Looser traits enforcing (run-time only, skip construction-time checks)
- `RandomConstraintDecomposer` edge cases
- `RoofDualityComposite` energy calculation
