High CPU usage for zero interval for missing events

[juacas]

It's not really a big bug because the function does what it says, but it can cause problems difficult to detect by the users

Describe the bug
When "interval for missing events" is set to zero Magic Areas consumes all the CPU in the thread of the event loop.

It impacts severely in overall HA performance.

Maybe other small values will behave similar.
To Reproduce

Select any area.
Configure interval for missing events to zero.
See the CPU performance and Magic Areas' debug logs.

Expected behavior
1- interpret 0 as "no checking of missing events". This is a common convention.
2- check for a reasonable range of values maybe related to "clearing interval".

Best regards.

This seems very reasonable. Added to the backlog

[jseidl]

This should be fixed by now as update interval is no longer configurable :P (solved itself)

[jseidl]

Misspoke, that's not the case, still valid issue

[jseidl]

I wonder if there's a use case for this option to be configurable. I'm split between adding limits vs removing this configuration option completely. Thoughts?
