FR: Zone/Channel List Selection

[nyaaaaaaatalie]

Proposing adding a zone/channel selection method to be able to select the channel from a list rather than scrolling through channels. This would require rework of both the daemon and client.

[W3AXL]

This would require the client & by extension the daemon to maintain a list of channels and zones, and additionally be able to correlate these to the zones/channels programmed into the connected radios. While not impossible, this would require a bunch of additional configuration work for end users on top of the rework of the daemon/client interface.

I'll leave this FR open for now but non-prioritized.
