Part of this code golf challenge, "Decode a Caesar ciphertext with high probability".

Sentences taken from a filtered and cleaned up subset of the MASC 500k corpus at https://anc.org/data/masc/downloads/data-download/ to which a Caesar cipher has been applied.

The dialect used for the CSV file uses "" to mean " in a "-enclosed string. This is the default dialect of Python 3.10's csv.DictWriter.
