Topojson

- changed class object to inherit sequence
- removed the `topojson.topology` function
- introducted the `topojson.Topology` class
- speedups and bug fixes, see 15 - 36
- introduced multiple options see 8

- apply linemerge on non-duplicate arcs
- fix computing topology without shared boundaries 1, 3
- use `geopandas` and `geojson` solely for tests, but recognize them as type 2, 4
- use [`simplification`](https://github.com/urschrei/simplification) as option to simplify linestrings
- include option to snap vertices to grid
- removed `rdtree` as dependency, use `SRTtree` from `shapely` instead

- initial release
