New Behavior

This builds on top of #1384

Time of day pieces are a new concept, where a rundown is able to define some pieces that should play at an absolute timestamp, no matter what part is active at the time.
This could be utilised to show some graphic about what is next, or to ensure that the outro is triggered at the correct time (doing so out of vision) to ensure it will be at the right point when the show reaches the end time.

These pieces can be returned from the getRundown blueprint method, and are very similar to pieces returned as part of a part. A few properties which are not relevant are removed, and the enable property must contain isAbsolute: true. This change allows the system to not need much special handling for them, with many of the differences based off this different start rule.

During playout, these pieces will be omitted from the timeline until ~30s before their start time. This duration is controlled by a new studio setting. Only once this point has been crossed will the pieces be considered for AB and lookahead. Sofie&playout-gateway coordinate regenerating the timeline at this 30s threshold, make sure to be running playout-gateway. (#1384 was written for this)

Other than that, these behave pretty much like normal outOnRundownChange pieces. They show in the ui in the current part, and in future parts once playback of the piece has started. They can be stopped/cleared by other pieces with the same rules as normal, and can be updated through the syncIngestChanges flow as usual.
