[Feature Request]: Consider adding sensor support

[peteGSX]

Problem/idea statement

I can see users potentially benefit from responding to sensor broadcasts, but also possibly sending sensor info in, for example enabling signals to be operated from a throttle.

Alternatives or workarounds

Signals can be operated via routes so that may not be the best use case.

Additional context

This may benefit from something like <JQ> being added to EX-CommandStation to retrieve all defined sensors in addition to having the delegate look for <Q|q> messages. Noting of course that <S> is presently implemented which will achieve this, but provides more data than required by a throttle.
