Installations instructions are either incorrect or not generic about hyddown

@mefuller
I suspect the symlink for pip points to a py2.7 installation also present on your system. Maybe try
pip3 install hyddown
or
python3 -m pip install hyddown
where python3 is the symlink to your python3 executable

There appears to be a bug in Fedora where pip, even when installed from python3-pip is defaulting to a python2.7 version,
but I believe the README should still be updated to reflect the need to use python3:

You will notice that while there is a file pip3, python2 has been totally deprecated and the pip command is exclusively the python3 variant (pip>21.0 should not have python2 support: https://github.com/pypa/pip)

I flied a bug report (https://bugzilla.redhat.com/show_bug.cgi?id=2004147) and have my output below for your review - do with it as you please, but perhaps simply providing $ python3 -m pip install hyddown as a workaround in case of a python2-related error would be a good update

@mefuller, I updated the README just as your pull request ticked in 👍 , but since your take is a little more elaborate I will accept the pull request

[mefuller]

I left the PR as a draft for now as I want to finish working though setting up and running a problem
