set commands for bypass

[Joemoe134]

Dear asillye, the current scripts do now allow to control the bypass status, something that would be great to control to increase efficient ventilation in summer time.
The modbus commands are no longer available via Ubbink website and the link to the dutch version of the manual is broken.
Any chance this was defined in there, but only never integrated in your project?
Thanks a lot,

Dear sillye, ubbink in belgium will provide a modbus manual upon request via email.
Bypass modbus addresses and settings are included.
I will give this a try.

I created a pull request with an implementation for that
