polylineencoder

Extend the API with a generic function to support all kinds of containers and C-style arrays.

Applying left shift operator on a negative value is an UB. The algorithm (step 3) describes how to properly encode negative values.

Make it compile with older compilers such as MSVC 14.x.

Move class template definition into the header file and remove source file. This will prevent linker error on client side. Polylineencoder is now a single header library.

This version of Polyline Encoder allows to configure coordinates precision. It's defaulted to the precision of five decimal places.
