Tools: add option to weekly log generator to only show a single day

Add a new CLI option `--date YYYY-MM-DD` to the weekly log generator. Using
it will make it ignore the `--weeks-ago` parameter, and just show the
activity for that specific day.

This is just something I personally found useful, to occasionally inspect
a specific date (WBSO daily log).
