Increase max/min frame range to over a million 

For some specific pipelines (e.g., holographic rendering) you can easily
need over a million frames (1k * 1k view angles).

It seems a corner case, but there is no real reason not to allow users
doing that.

That said we do loose subframe precision in the highest frame range. Which can
affect motionblur. The current maximum sub-frame precision we have is 16.
While the previous limit of 500k frames has a precision of 32.

Thanks to Campbell Barton for the help here.
