Testing samples/gem_host.py and samples/gem_equipment.py

[twmr]

Hi! Thx a lot for this great library!

I'm curious if the host and equipment examples in the samples/ dir can be run on the same host to test basic streaming functions.

What I currently get when I run both samples on the same host is an Address already in use exception in the sample that is started last. This is with secsgem v0.1.0 (BTW With the version from the main branch I get different exceptions).
