Investigate how `pip` translates `requirements.txt` and gets packages from the PyPi Index

[Kiwifuit]

Related to #7 and #8, just that we need to translate the requirements,txt file (and maybe give it a easier usage in the CLI, something like pip.rs install-requirements or something like that) so that we can get the package the requirements.txt file requires from the PyPi index

Notes

• https://pypi.org/pypi/PACKAGE/VERSION/json according to the official docs on this API

Problems

• Version Operators (e.g. ==, >=, etc.)
  • The JSON API does not support this
  • Probably not a big issue here, as there's no rate-limiting
  • I also don't know if pip supports the other operators besides ==
• Python version verification
• A robust way to parse requirements.txt
  • Very doubtful that this actually works, so half a tick

@DevChaudhary78 How do I do that?

@Allstreamer's pull about the JSON API could handle the grabbing the URL to the wheel part

[Allstreamer]

There's no ratelimiting on the API so it would be an easy way to get information for packages / the wheel_url
