Script to anonymize/deanonymize appraisal data

[countvajhula]

Extracted from #2 (comment)

Based on the proposed syntax change in #5 :

  * [comma, separated, contributors] An anonymized contribution was done [allocation]

... it would be great to have a CLI script to (1) anonymize and (2) deanonymize a provided input file that uses this syntax.

This could be done by just stripping/adding the contributors portion (note that we can't do this with the current syntax as we need to change from active voice to passive voice, etc.).
