Cleaning Hasseb driver

[dgomes]

Finally got sometime to upgrade my setup with Hasseb controller.

The driver has these orphan imports

Also of note:

• It requires pyhidapi

From a previous PR from @hasseb :

"To install pyhidapi:
git clone https://github.com/awelkie/pyhidapi.git
cd pyhidapi
sudo python3 setup.py install"

This is important as this library is not available as a pip package... can we replace this by something more standard @hasseb ?

Propose https://github.com/apmorton/pyhidapi

I will try if I get it work with both Windows and Linux, it may also work with Mac which would be nice as well.

@sde1000 could you possibly make a 0.7.1 release to include this fix ?

@hasseb Hello, can you somewhere on wiki add information about update firmware for your devices?
I mean, move somewhere to website this
