Only get one day's worth of chores

[ddbruce]

I'm not sure if this is possible, but with a filter, can we get a single day's worth of chores based on today's YYYY-MM-DD date? I did try initially when writing it, but it was very difficult for me to understand how Google's filtering works via the API.

This can be added to #15 if it's possible.

There does seem to be a way to only grab data based on the a1 range. I'll need to look more into it. More info can be found here: https://developers.google.com/sheets/api/reference/rest/v4/DataFilter
