Support rules that override button holds

[pcdiem]

Description:

Add support for rules that override button holds. Because the hold time of buttons in PWM Dimmer is different than the SetOption32 value, button hold are processed outside the normal Tasmota button processing. This PR adds support for checking to see if a rule is active that would override a button hold. If there is, the button hold is not processed by PWM Dimmer.
