Add feature to detect Mbtiles format (#713)
Feature for `Mbtiles` struct to detect which format a `.mbtiles` file is
in according to the [MBTiles
specfication](https://github.com/mapbox/mbtiles-spec/blob/master/1.3/spec.md#database).
The function `detect_type` identifies whether the `.mbtiles` file
contains a `tiles` _table_ OR if it contains `map` and `images` table
(which provide the data for a `tiles` _view_).
