Cannot install dotenv dependency

[peterdesmet]

vph5_to_vpts requires dotenv, but it seems the installation fails:

vph5_to_vpts

Make sure you install pip install python-dotenv instead.

Thanks that worked, the issue was that I hadn't installed the optional dependencies with:

pip install vptstools[transfer]

Since that command throw an error:

pip3 install vptstools[transfer] 
zsh: no matches found: vptstools[transfer]

Turns out I need to escape for zsh (rather than bash):

pip3 install vptstools\[transfer\]

Would the escaped commando also work for bash? If so, I would update in the README
