Add an option for the Visvalingam simplification algorithm (#16)

Browse Source 
* First attempt at porting Paul Mach's Visvalingam implementation

* Make indent

* Mostly working

* Approximate equivalence from Douglas-Peucker to Visvalingam levels

* Don't simplify away tile boundary crossing points

* Add a command-line option and test for Visvalingam simplification

* Update changelog

* Cleanup in response to review feedback

* Include <stdio.h> to fix compiler warnings
