[feature] Consider deprecation of HDF5

[drobnyjt]

Is your feature request related to a problem? Please describe.
HDF5 is a widely used data format. RustBCA includes partial support for HDF5 input. However, requiring an external installation means that it is difficult to maintain, and the Python interface may supplant any use-cases for HDF5 in integrated modeling.

Proposed solution
Deprecate HDF5 feature and remove all related code.

Alternative solution(s)
Review HDF5 feature and bring all code up to an acceptable standard.

Additional context
I am currently unaware of anyone using the HDF5 input feature. I would consider maintaining it if a user comes forward asking for it to be kept.
