Adding "anystr_lower" to config
# Feature Request

     optional deps. installed: ['typing-extensions', 'email-validator']

```
Just like there is "anystr_strip_whitespace" in the config, which runs .strip() on any string value, I would like to add "anystr_lower" which would run .lower() on any string value.

I just find myself use .lower() on the strings in many validators in places in my code, so I thought it would be useful to add it to the config, I assume that was the use-case of "anystr_strip_whitespace" as well.

If this is fine I'll gladly implement it myself, looks like it's a small change.
