"Year ago today" nostrscript

[jb55]

Environment inputs:

• Current time

Simply generates the filter:

nostril query -r -k 1 \
  --since $(date +%s -d 'now - 1 year - 12 hours') \
  --until $(date +%s -d 'now - 1 year + 12 hours'))

Idea:

• This could be considered a nostrscript filter "constraint" that could be applied to any other query.

This doesn't technically need to be in nostrdb, maybe this makes more sense to be a higher level thing that is simply passed to nostrdb.

For everything else:

• Filter and reducer queries #33
