Call pazusoba.so with cdll

[HenryQuan]

Currently, python is using the binary via command line and pazusoba writes the final route to the disk. This works very well but it isn't ideal because file I/O takes time. If python calls pazusoba via cdll, the data can be sent to python directly and python can simply read it and ask pazusoba to free the list. pazusoba will be compiled to a shared library as pazusoba.so. However, this is not possible unless pazusoba supports it.

WIP

• Make pazusoba.so with cmake
• Add a python wrapper
• Pass data to the shared library
• Receive the route from the library
• Update cmake so that the output is libpazusoba.so on all platforms

All good for now. However, not yet finalised but it is working.

This is done in dev.
