[Enhancement] Report zone specific system trouble to the zone instead of the panel

Report zone specific system trouble to the zone instead of the panel?

Describe the solution you'd like
Currently this sends a zone specific system trouble to the panel, which the zone number:
'system_trouble_status': 'AC Fail, Box Tamper zone 8, Fail To Communicate, EEProm Memory Error'
I was going to add support for reporting this to a zone in my ISY integration, but was wondering if we could change elkm1_lib to report these to the zone instead of users having to parse the 'zone ' string?

Describe alternatives you've considered
Parse the string to get the zone number out of the 'zone '.

Additional context
Let me know what you think, if you would prefer to keep it as is then we can close and I will handle it on my end.

I'm open to considering this. What are your thoughts on how to handle when a zone has multiple trouble conditions?

I'm not sure the best way to handle it, The way it's handled on the panel makes sense where the user is sent a comma separated list, but it's really not ideal. It would be nice to just have properties available for each, but I understand why all are sent in at the same time, so it works. I was thinking it should be done the same way for zones unless you have better ideas?
