breaking changes
Localization has been turned off by default, so django's `localize` function will no longer be called on values before they are exported. This is considered a breaking change. The decision was made in light of the fact that CSVs exist first and foremost as a data exchange format, while localization increases human-readability at the expense of machine-readability. This was modified in response to a need presented by a downstream project.
