Some major changes

Yes it jumped from 1.1 to 2.1 because commits are version to me

You can now have a camera struct:
declare it with PelcoBus::PelcoCam
and change it's setting (address and disable ack)
Also the main class is now for all the Pelco bus so it can run multiple camera

You can also disable acknowledge, useful when you are working with cameras with RS422 and uses 2 pair of cables but you have only 1
