MongoDB Data Anonymizer v0.1.2 Release

We are excited to announce the release of MongoDB Data Anonymizer v0.1.0. This version introduces the ability to anonymize specified fields in MongoDB collections and copy them to a target database. It includes a command-line interface for easy usage. The anonymization process can be customized with options such as specifying the collections to anonymize or ignore, and setting the batch size for processing documents. This release also introduces the + and - modifiers for the fieldList option, allowing users to add or remove fields from the default list respectively.
