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
PMTiles is a web-optimized format, allowing the actual file to be read
with HTTP range requests. Supporting this use case instantly allows
Martin to function as a lambda executable accessing PMTiles, but without
any significant investment into devops or hosting large file.
PMTiles config now also allows `http` and `https` protocol.
```
# Publish PMTiles files
pmtiles:
paths:
# specific pmtiles file will be published as mypmtiles source
# (use last portion of the URL without extension)
- http://example.org/path/to/mypmtiles.pmtiles
sources:
# named source matching source name to a single file
pm-src1: https://example.org/path/to/some_pmtiles.pmtiles
```

This implements dynamic font protobuf generation, allowing users to
request font ranges on the fly, and combining them in any order, e.g.
`Font1,Font2,Font3`, same as with sprites and tiles
This is a first iteration, without any multithreading support. In
theory, this could be done far faster by generating SDFs with multiple
threads.
### Current process
* during init, figure out all glyphs available in each font, and store
them as a bitset
* during request:
* combine requested bitsets to figure out which glyph should come from
which font file
* load those glyphs from files (using a single instance of the freetype
lib)
* convert them to SDFs and package them into a protobuf

* Remove `--disable-bounds` flag and `disable_bounds` config parameters.
* Add `--auto-bounds` / `-b` CLI parameter and `auto_bounds` config
value:
* `quick`: Compute table geometry bounds, but abort if it takes longer
than 5 seconds (default)
* `calc`: Compute table geometry bounds. The startup time may be
significant. Make sure all GEO columns have indexes
* `skip`: Skip bounds calculation. The bounds will be set to the whole
world
* `-b` is now mapped to `--auto-bounds` param, but it will fail if used
by itself because it now requires a value.
