Improve performance of LcaDataLoader

[uo-lca]

Was able to reduce run time loading all LCA_Data files by about 50% (20 -> 10 min. on dev computer). Most significant reduction comes from disabling AutoDetectChanges when a large number of entities are added and not updated. Relevant commits:

• DB: Optimize load Classification.csv
• DB: Disable AutoDetectChanges during ILCD archive load

Keeping this issue open because I plan to make more improvements later.

Reduced run time by another 50% (10 -> 5 min. on dev computer) by caching a mapping of UUID to internal ID (FlowID, ProcessID, etc.).
