mbtiles summary tool cleanup (#1000)

After some thinking, it seems `mbtiles summary` (aliased as `mbtiles info`) would be a bit better than stats. I renamed and adjusted documentation, consolidating it in one doc page. Other changes: * use file system's file size, reporting 'unknown' if needed * report page count * moved bbox computation into a separate function * inlined a number of things for readability

+Use `mbtiles summary` to get a summary of the contents of an MBTiles file. The command will print a table with the number of tiles per zoom level, the size of the smallest and largest tiles, and the average size of tiles at each zoom level. The command will also print the bounding box of the covered area per zoom level.
