Alex Hall 083a0ec000 (core) Allow using MIN and MAX functions with dates/datetimes
Summary:
The MIN and MAX functions for formulas previously only considered numbers, ignoring other types, including dates. An example of this being a problem is here: https://community.getgrist.com/t/last-field-circularreferror-what-is-it/1114/4 . Using `MIN` on a column of dates would return 0 (the default) which gets converted to 1970-01-01. Users have to use `min` instead, which is confusing, and doesn't work when some values are empty.

This diff lets the functions operate on date and datetime values. A mixture of dates and datetimes is allowed, even though these cannot usually be compared in Python. Mixing dates and numbers will raise an exception.

Test Plan: Extended doctests
