Use maps instead of arrays to boost deduplication speed #56

Sometimes buffer views and accessors arrays have more than 1 000 000 items. This particular optimization allowed us to reduce deduplication time from ~11 hours to ~1 minute on one of our files.

Wow! Now I feel silly for having used arrays in the first place... Thank you @VFedyk!
