`pybluez` install instructions

[Alystrasz]

I struggled to run the powerspycli script on my install (Ubuntu 23.10, Python 3.11.6) due to the pybluez dependency install instructions being somehow deprecated, so here's what I've done to make it work.

---

Installing pybluez through apt is not possible (package not found), I tried to install it with pip, and got the following error:

(powerspycli) remy@chimay:~/Travail/powerspycli$ pip install pybluez
Collecting pybluez
  Downloading PyBluez-0.23.tar.gz (97 kB)

      error in PyBluez setup command: use_2to3 is invalid.
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.

According to https://github.com/themagpimag/magpi-issue61/issues/1#issuecomment-507239119, libbluetooth-dev install is required in order to install pybluez:

sudo apt install libbluetooth-dev

pybluez install would still fail at this point:

(powerspycli) remy@chimay:~/Travail/powerspycli$ pip install pybluez
Collecting pybluez

I had to install pybluez from its repository directly:

pip install git+https://github.com/pybluez/pybluez.git#egg=pybluez

Thanks. We were using Ubuntu 20.04 so far in our classes and didn't notice the instruction aren't valid for the latest Ubuntu versions. I'll update the readme with these instructions.

Development on pybluez seems to have stopped, so we should start exploring alternatives for this script.
