Consider using builtin importlib.metadata

[EvaSDK]

Using pip show to collect package metadata only returns a select few metadata of a package. Using importlib.metadata would allow accessing to all of them, such as Download-URL, Project-URL, and Maintainer. See https://packaging.python.org/en/latest/specifications/core-metadata/. This should make the code slightly faster and more reliable.
