create-subset command for creating a publishable subset of a photos database

[simonw]

I want to share a subset of my photos, without sharing everything. Idea:

$ photos-to-sqlite create-subset photos.db public.db "select sha256 from ... where ..."

So the command takes a SQL query that returns sha256 hashes, then creates a new file called public.db containing just the data corresponding to those photos.
