Building on Arch requires installing python-pyserial

[slzatz]

Instructions say install python2-pyserial but my experience is that won't build on Arch without python3 pyserial

I've newer tested the build on Arch Linux.
The prerequisites for Arch were taken from esp-idf documentation.
If you had to install anything else to make it work on Arch, could you, please, post the needed packages, and I'll update the instructions.

Just add sudo pacman -S python-pyserial and everything works fine. The default python on Arch is python3.x. It's possible that python2 is being called explicitly somewhere so I didn't remove the python2 pyserial although I am not sure it is actually needed.

Ok, added.
