Timerange Switch / time of day, day of the week

Have a look at https://discourse.nodered.org/t/two-subflows-i-made-a-timerange-switch-and-a-scheduler-dashboard-integratable/24586 for examples and more info.

Lets through or blocks a payload based on a time range. This can either be configured through the enviroment variables in the node ui or as described below with a message that has an override topic. If in range the msg will be passed to the first output and otherwise to the second. The start and stop time needs to be defined in an hh:mm format. There is also a week array. The week starts on monday so 4 for example is Thursday. Payload will only be passed on days that are in the array. Out of time range payloads will be redirected to the second output. The schedule can be overriden by injecting a message with the topic of "override" that contains a msg.payload object with the keys of "start","stop","days" like this:

    "start": "10:00",
    "stop": "14:00",
    "days": [

Start and stop need to be strings in the hh:mm format and days an array of numbers as described above. The override can be deleted by injecting a msg.payload string "reset".
