Removed section_k_band normalized, as it can be simply constructucted from section_k_band with a shift stored in energy_reference_highest_occupied. Made section_encyclopedia to store references into the band structure instead of constructing own copy.

Modified the Encyclopedia normalizer to skip storing a full copy of the band structure and DOS because they are fairly large. Instead they are ingested directly from the archive using a simple reference.

Removed unnecessary JSON serialization from encyclopedia metainfo, changed periodicity to be a boolean array.

Added structure_type, structure_prototype and strukturbericht_designation to EncyclopediaNormalizer.

Added formula and formula_reduced to EncylopediaNormalizer. Cleaned up the function for forming the Hill notation.
