Provider for conan package manager versioning

[rols121]

Description

A provider for the conan C++ package manager would be great.

Possible Solution

I had already forked the commitizen repo and started working on this before I read the contributing section docs. I have attached a patch for a proposed solution which includes tests for the provider. conanfile_provider.patch

A simple

git apply conan_provider.patch

In the root of the commitizen repo should apply the patch (Hopefully if master has not moved on).

Conan has recently moved to version 2. Version 1 is on a deprecation path, but people and organisations are still using version 1. The version of the project in both versions is in a conanfile.py which can be in the root of the project directory. The proposed patch
