Bool: CAPS Enum Labels for h5py

Else it does not identify those as `bool_` but as `int8`.
Regression for ComputationalRadiationPhysics#153 (still in `dev`).

Increases format by a minor since the structure is still
the same but the identification in `h5py` is improved
(and it is still not in a stable release).
