Protocol updates with NUT v2.8.0

Cheers, noticed this binding project - thanks for making one :)

Just wanted to let you know that among changes leading up to NUT v2.8.0 release earlier this year, there was aliasing of master to primary (and slave to secondary) in docs, config files, protocol commands, etc. The implementation is supposed to be backwards compatible, so newer clients can talk to older servers and vice versa, but you might want to update yours along the lines of https://github.com/networkupstools/nut/blob/e7f9e0fb425622818745d1e7ef85b1c81846af8a/scripts/python/module/PyNUT.py.in#L348-L358

And just FYI: Posting a link to your project on https://networkupstools.org/projects.html - should be updated soon :)
