Add a top level config parameter -- the size of cache memory (in MB) to
use for caching tiles and PMT directories, defaulting to 512, and 0 to
disable. This also removes the `pmtiles.dir_cache_size_mb` parameter (it
will be ignored, but will give a warning)
```
cache_size_mb: 512
```
The new cache will contain all tiles as provided by the source. So if
PostgreSQL returns a non-compressed tile, the cache will contain the
uncompressed variant, and will be compressed for each response. This
will be fixed in the later releases.
Note that fonts and sprites are not cached at this time, and are still a
TODO.
* Make it possible to have configuration specific to the file-based
config sections: pmtiles, mbtiles, and sprites.
* Implement PMTiles directory cache shared between all pmtiles (both
http and local), with configurable max cache size (in MB), or 0 to
disable. Defaults to 32MB (?)
* PMTiles now share web client instance, which optimizes connection
reuse in case multiple pmtiles reside on the same host
* Major refactoring to allow modular reuse, enabling the following build
features:
* **postgres** - enable PostgreSQL/PostGIS tile sources
* **pmtiles** - enable PMTile tile sources
* **mbtiles** - enable MBTile tile sources
* **fonts** - enable font sources
* **sprites** - enable sprite sources
* Use justfile in the CI
Fixes#1093
* BREAKING: `martin-cp` will now set `format=pbf` instead of `mvt`. This
is what QGIS and possibly others expect, and this is what tools like
tilelive generates.
* `martin-cp` sets `minzoom` and `maxzoom` metadata values based on the
zoom parameters
* Add `mbtiles meta-update` command to refresh zoom levels based on the
present tiles.
Partially addresses items in #1081
Mathematics should be consolidated in the utils crate. Eventually, I
hope we will move it to [tile-grid](https://crates.io/crates/tile-grid)
or [utiles](https://crates.io/crates/utiles) crates and consolidate our
efforts there.
Also, modify earth circumference by a few centimeters (to match various
other implementations): from `.7` to `.685_578_5`. This modified a few
unit tests.
* Now by default mbtiles will not print internal warnings (e.g. that
something is taking too long to execute)
* remove mbtiles --help test - not really needed, but adds complexity
because it has to be updated every time a version changes.
* 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

* remove benchmarks - not used for now, will need to be rewritten
* move some CLI settings to a separate struct
* move config saving to a shared function
* simplify zoom level CLI parsing
* rename main.rs to be the same name as generated binary (we can have
multiple bins later)
