Ability to specify universal2 wheel packages in a marker

[danrossi]

I've been trying to get locally merged universal2 wheels working for packages that don't supply them I ran into many bugs getting them installed via pipenv. But have run into another issue where installing httptools installs the arm64 version when the universal2 wheel is required.

A marker to specify that would be nice if not documented.

I have to then download the specific wheel like the others and set it up for installation in Pipenv but found a bug where it won't choose the local wheel and has to be installed manually.

I tried

pipenv run pip install --implementation py httptools 

but failed

It currently looks like this in the Pipfile but should be specific for macos

httptools = "*"
