Add support for expiring files
SUPPLEMENTALLY:
- Add an `expiration` field to the `file` table of the database
- Produce a migration for the above change
- Overhaul the cleanup script, and integrate into fhost.py
  (now run using FLASK_APP=fhost flask prune)
- Replace the old cleanup script with a deprecation notice
- Add information about how to expire files to the index
- Update the README with information about the new script

Squashed commits:

Add a note explaining that expired files aren't immediately removed

Show correct times on the index page graph

Improve the migration script, removing the need for --legacy

Use automap in place of an explicit file map in migration

Remove vestigial `touch()`

Don't crash when upgrading a fresh database

Remove vestigial warning about legacy files

More efficiently filter to unexpired files when migrating

THE NULL POINTER
================
{% set fhost_url = url_for("fhost", _external=True).rstrip("/") %}
HTTP POST files here:
curl -F'file=@yourfile.png' {{ fhost_url }}
You can also POST remote URLs:
curl -F'url=http://example.com/image.jpg' {{ fhost_url }}
Or you can shorten URLs:
curl -F'shorten=http://example.com/some/long/url' {{ fhost_url }}
File URLs are valid for at least 30 days and up to a year (see below).
Shortened URLs do not expire.
Files can be set to expire sooner by adding an "expires" parameter (in hours)
curl -F'file=@yourfile.png' -F'expires=24' {{ fhost_url }}
OR by setting "expires" to a timestamp in epoch milliseconds
curl -F'file=@yourfile.png' -F'expires=1681996320000' {{ fhost_url }}
Expired files won't be removed immediately, but will be removed as part of
the next purge.
