Improve the efficiency of "vcgencmd get_throttled" by directly requesting
the status from the user space driver using ioctl. This should reduce CPU
spikes that result from forking the current process.

Temperature Monitors may report null values as temperatures,
thus special handling is needed. This commit also reworks
temperature store updates to use the subscription cache
rather than perform its own caching of "last temps".

Now that all subscriptions are cached it is no longer required for
the paneldue component to cache its own printer state.

This callback will only fire after a component has requested
a subscription, preventing early updates while the component
is waiting for the subscription request to complete. It is still
valid for components to register the "server:status_update"
event handler if this behavior is not a concern.

It is possible that a subscripition request can occur between
after Klipper updates a field's status, but before it pushes
a status update to the connection. The result is a race
condiiton where the response to the subscription request
contains the lastest state but it is not propagated to
currently connected clients.
This is resolved by caching subscripiton data, diffing it
with the response to the subscription request, and
manually pushing the diff.

Wrap a Future instead of an Event, as we don't need to notify multiple
waiters. Additionally the future can return responses and raise exceptions
directly.

The subscripition request is reentrant in Klippy. Sending multiple
requests from the same connection may create a race condition,
so use a lock to prevent reentry.

A previous bug in the webcam module could have set boolean
values as integers. Make sure they are type correct when
reading webcams from the db.

In Python a "bool" is a subclass of int. When introspecting
a webcam's attributes it is necessary to check for booleans
before integers.
