Don't hash files with same inode identifiers more than once #142

Closed pkolaczk closed 2 years ago

pkolaczk commented 2 years ago

This optimization speeds up processing if the file tree contains symbolic or hard links. Symbolic and hard links to the same data will be hashed at most once. The algorithm is also smart enough to not hash the data at all, if it determines that no other (unlinked) matches are possible.

Fixes #139.
