Replace mapwarper with self-hosted 1930 Manhattan Atlas (#1277)

Tiles are compressed to webp. Webp is now well supported.

One oddity is that I pulled different zoom levels at different times.
Some in 2023, some recently. They seem to have different crops. Maybe
someone updated some of the plate cropping. So when you zoom some crops
can change.

They are served by Cloudfront with http/2 which allows more tiles to be
loaded simultaneously.

Mapwarper has been having intermittent DNS issues for me and not working
a lot of the time.

⚠️ In 2020 I tried directly proxying Mapwarper on using Cloudfront with
edge compression. It was incredibly expensive. I believe the main costs
were the outbound bandwidth from the internet for the soruce, while this
uses s3 which has no bandwidth cost. Watch costs!
