Implement http pmtiles (#991)

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
 ```

fixes #884
