Fix #38 by always clamping dates to a sane value for the given period. Previously the targetted desired date for a given retention period would depend on the day the backup was performed. As a result it shifted each day by one day causing unstable intervals in between. So a weekly retention period interval could be vary between 6 to 8 days. For example weekly backups are now clamped to sundays (hardcoded, #39) and as a result the best matching snapshot no longer shifts day by day. This uses dateutil to perform the weekday clamping. Add Django 3.1 as a supported version in the setup requirements.

Would be nice to be able to specify on which day the weekly backup should be created (or, as bonus, time?). This can be nice in combination with other backup strategies for e.g. MariaDB, where we do weekly backup of databases on sunday (+ binlogs every day to cover the whole week).
Creating a weekly backup in planb on saturday (or sunday before mariadb backup if time option = yes), would then give us the mariabackup + binlogs till saturday/sunday.
