ACEtk data generation for electron library

[melekderman]

Summary of changes

Adds an electron data library generator that converts EPRDATA14 ACE-format electron/photon/relaxation data into MC/DC's HDF5 format for continuous-energy electron transport. The generator mirrors the structure of the existing neutron data generator, producing per-element HDF5 files (Al.h5, etc.) under an electron_reactions/ group with MT-numbered reaction channels (MT-526 bremsstrahlung, MT-527 excitation, MT-528 elastic, MT-534+ ionization per subshell) and a separate atomic_relaxation/ group for fluorescence and Auger transition data.

Is this ready for merging, @melekderman?

Hi @ilhamv,

I’ve made some changes and updates:

• I’ve created separate folders for different particles (neutron and electron for now).
• I’ve fixed some name mismatches.
• I’ve updated a few outdated README instructions.

It’s ready to merge after your review.

One more thing, I believe we should add a script to the top folder (data_library_generation) so that users can prepare multiple datasets (nuclides and elements) or a dataset for multiple particles (e.g., electron and photon in the same file). What are your thoughts on this?
