[FEATURE] Use grayskull with any pypi mirror/server

Is your feature request related to a problem? Please describe. As per my reading and testing of this tool, I do not think it is is possible to make a conda recipe out of any pypi mirror just out of the official one (ref to code: https://github.com/conda-incubator/grayskull/blob/d72b59804ab6800d18f1cef40c03ff22565ff2b2/grayskull/pypi/pypi.py#L40). Describe the solution you’d like I would like to be able to use grayskull to make conda recipes out of any python package listed in any arbitrarily provided pypi mirror or even locally. Perhaps by having a CLI command option:

grayskull --mirror https://pypi.myenterprise.com <python-package-name>

Describe alternatives you’ve considered Building a conda recipe manually and having undesired behaviours.

Is this line: https://github.com/conda-incubator/grayskull/blob/d72b59804ab6800d18f1cef40c03ff22565ff2b2/grayskull/pypi/pypi.py#L40

The one actually responsible for grayskull looking in pypi.org only? If I changed that one to my entreprise pypi server would it work?

It will depend if your enterprise pypi server will return the metadata correctly. If they return it like pypi it will work, otherwise I am afraid that might not work But it is on my plans to also generate the recipe from sdist packages located anywhere, that will solve your problem as well
