Add option to show more clock numbers using ClockIncrementHourFormat

[danielmessi13]

This is a request for a new functionality, basically we would have a ClockIncrementHourFormat class, just like the existing one: ClockIncrementTimeFormat, this class would be passed to the existing clockNumberDecoration, so we could have more times displayed visually, for example:

So basically it would show text showing the time every two hours: 0h 2h 4h 6h 8h 10h 12h 14h 16h 18h 20h 22h

@danielmessi13 You may use clockIncrementHourFormat <- TimePickerClockNumberDecoration to achieve this with the latest version.
