conan.io C++ packages need to be recognized as registry

[mattkretz]

https://github.com/NLeSC/awesome-research-software-registries lists https://conan.io for C++, but howfairis does not recognize projects that are available through Conan.

The solution seems to be a simple

While recognizing conan badges is simple, fixing the tests to not fail after the change is way more complex. I could use some help there. I tried to adjust the expected snippets and add a test_has_conan_badge function to test_checker_.... But now pytest errors out with 'UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc5 in position 18: invalid continuation byte' all over the place. Even after switching back to the 'main' branch with a clean 'git status'. I'm no Python expert... how do I reset this thing without starting over completely?

[mattkretz]

Oh, the tests pick up vim's .*.swp files (binary) and try to interpret them as utf-8. Not helpful.

[mattkretz]

OK, managed to adjust the tests. IMHO, adjusting tests for a new badge is way too complex.

May I open a PR?

Hi @mattkretz, thanks for reporting this. Let me ping @fdiblen and @c-martinez for you, they might be able to tell you how best to go about this.
