Conan v2 (#2805)

* Removed Conan1 build.py file using conan package tools that are no longer supported

* Working conan 1 and 2 build with the test package. 

updated the test_package to be updated to conan 2 and fixed missing cmake. Still need to check that the license file is packaged up and that the packages look identical before the changes

* Removing debug prints and the license check that isn't working yet

* Working license file copied over as it was before

* Migrated the properties of cpp_info to conan 2. Keeping conan 1 support by checking the version of conan

https://docs.conan.io/1/migrating_to_2.0/properties.html

* Revert "Removed Conan1 build.py file using conan package tools that are no longer supported"

This reverts commit a606d1dfe6.

* Need to add a set_version to parse the version from CMakeLists.txt

Adding a package build yaml to ensure conan keeps building on 1 and 2

* Setting lowercase catch2 for pkg_config and cmake_target_name

* Fixing the namespace for conan file cmake_target_name
