Scale ADT variables by time

[e-lo]

Currently we have a dummy variable for "large projects" that uses ADT, but right now the function uses the raw forecast value, which could be hourly.

Could do this simply:

• multiplying the ratio of the seconds in the day to the seconds between start and stop time

But realistically this isn't right b/c most counts are for peak hour.

Will likely assert hour-by-hour distributions of daily traffic and use that as a "good enough" for creating a dummy variable.

Also note that some variables shouldn't be summed across the day, so will need to do a check on the variable.
