Related issue: #122

How I did it

glob ~/.solc-select/artifacts for installed solc binaries.

How to verify it

$ rm -rf ~/.solcx ~/.solc-select
$ pip install solc-select
[...]
$ solc-select install 0.4.26 0.7.6
Installing '0.7.6'...
Version '0.7.6' installed.
Installing '0.4.26'...

$ python -c 'import solcx; print(solcx.import_installed_solc())'
[Version('0.7.6'), Version('0.4.26')]

I am not sure on how to add test cases for this and whether this is even needed?

Somewhat related: it might be a good idea to use symlinks when sharing a lot of solc versions with solc-select. But I am not sure, whether this results in other issues.
