refactor: Drop support for yaml-cpp old API

[aguenette]

fix #42

So, here's my attempt to upgrade libpointmatcher's yaml-cpp dependency to its new API.

As discuss in #42, libpointmatcher will no longer provides yaml-cpp sources in the contrib directory, which mean that Windows users will have to build and install yaml-cpp from sources.

I've followed this tutorial to upgrade the API.

Changes:

• Use the new yaml-cpp API, i.e. version 0.5+.
• No longer provide sources in the contrib directory.

Tested on:

• [x] Ubuntu 18.04
• [x] Ubuntu 20.04
• [ ] Windows

However, these changes need to be tested on Windows, so if a Windows user feels generous and is willing to test them, it would be greatly appreciated. 😄

Any suggestions are welcomed. Thanks!

Hi @xlla! On Ubuntu 18.04, all the tests pass. So, I'm not sure that the problem comes from the refactor of the yaml-cpp API. Have you tried to run the tests on the master branch (i.e. using the old yaml-cpp API)? If not, can you please try it and tell me if you get the same tests failure? It's just to be sure that it's not related with the changed from this branch. Thanks!
