Remove redundant lemmas found with clean.sh

[goodmami]

Also add files that log the changes made.

This removes redundant lemmas with the following procedure:

1. Normalize the lemma
   a. Strip quote pairs at the beginning and end of the lemma
   b. Replace each underscore in a lemma with a single space
   c. Strip any spaces at the beginning and end of the lemma
   d. Store the normalized form if it differs from the original
2. Remove Redundancies: If multiple lemmas with the same synset identifier (offset + pos) and lemma type (e.g., fra:lemma) are the same string after normalization, only one is kept.
3. Log Changes: Write a log indicating which lemmas have been REMOVED or MODIFIED. Wordnets without a log file did not have any changes.

Also note:

• This PR does not fix all issues that were noticed during the creation of the deduping scripts:
  • GAP! and PSEUDOGAP! entries #45
  • Inconsistent lemma row types for Arabic wordnet #46
  • HTML anchors in French lemmas? #47
  • Possible duplicates in the Arabic wordnet #49
• An entry being modified does not mean the result is correct (they may contain other kinds of errors).
• This PR does not remove all redundant lemmas. Lemmas that differ only by casing or diacritics are not removed as this will probably need manual review.
