Fixed submodule reference, added check for requiring symmetry information before processing bulk systems in EncyclopediaNormalizer.

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.

Fixed strukturbericht_designation and structure_type in EncyclopediaNormalizer due to update in AFLO prototype data.

Changed the hashing to use the nice function within nomad.utils. Also the hash lengths are now different based on the expected complexity of the input space.
