* Use gzip compression for MVT tiles by default
* Allow user to set compression with `--encoding` parameter (same as
browser's header, e.g. use `br,gzip' to encode with brotli as first
choice, unless already encoded as gzip)
* Allow user to pass a query to the Postgres functions with
`--url-query`
* A bit of a cleanup for `mbtiles summary` output
- Add separators to long literal.
- Use first() instead of get(0)
- Move some SQL-making code to their own functions
- Minor mathematics and rounding cleanup
