Time of Day, Month, Day of Week Filters

[ncthbrt]

Describe the solution you'd like
I'd like to be able to scrub and filter time by more than just the timestamp. Filtering by a range of time of day, month of year, and day of week all have the potential to reveal patterns, especially when working with commuter patterns and seasonality.

Describe alternatives you've considered
Adding additional fields (such as day_of_week) to input is a viable alternative, but hampers exploratory data visualisation as you have to manually add it to data before you start working with it.

Questions around the design of a solution to filtering are:

1. Should this be a set of new filters or integrated as an option in the existing time filter
2. Does the way that deck and kepler process data allow for more complex queries than a simple range.
