pip Install method with kalamine fails on ubuntu 20.04 (v0.9)

[doc75]

I just tried to install the version 0.9 on a machine that had v0.8 (not sure if it has an impact).
Here is what I did:

• wget https://qwerty-lafayette.org/layouts/lafayette.toml
• pip install --user --upgrade kalamine
• PATH=/home/<user>/.local/bin:$PATH
• xkalamine install lafayette.toml

It raises the following error:

File could not be parsed.
Error: 'bytes' object has no attribute 'suffix'.

I then tried the pipx install like this:

• pip uninstall kalamine
• pipx install kalamine
• source /home/>user>/.local/pipx/venvs/kalamine/bin/activate
• sudo env "PATH=$PATH" xkalamine install lafayette.toml

And it works

Not sure if there is bug in the first method or if instructions need to be updated.
