Geoip middleware to restrict users to a set of allowed countries
This middleware uses Django's Geoip support (https://docs.djangoproject.com/fr/2.2/ref/contrib/gis/geoip2/), as well as axes's package helper to retrieve IP address (since Django's REMOTE_ADDR might be wrong when behind a reverse proxy). Ensure your geolite DB files are up to date (eg. with https://djangosnippets.org/snippets/10674/). The checker is optional, but ensures that security is not broken due to a misspelled/missing GEOIP_COUNTRY_WHITELIST.

Strict Boolean Form Field
A form field for a Boolean that forces the user to make a choice from a list of choices. **Use Case** You have a Yes/No question the user must answer, but they may answer it yes or no. You don't want to supply a default because your need to force the user to actively select their answer. If they do not select an answer, the field should raise a validation error, like "This field is required". Normal BooleanField logic is based on a "checkbox", which, when "required" is required to be checked. This logic assumes that an empty value is the same as False -- in fact, there is no way for validators to distinguish between the empty value and False. Based on excellent suggestion from Peter DeGlopper: https://stackoverflow.com/a/56677670/1993525
