Color Correction Ranges are clamped from 0-1

[RichardULZ]

Problem

On the Color Correction node, the highlight selection range is clamped from 0-1.
This makes softly selecting and grading highlights of exr renders or hdr images hard.

Expected behavior:
Using the highlight control of color correct to softly pull down bright highlights on exr renders, by extending the highlight range above 1

Actual behavior:
The highlight range is clamped and will stop increasing power on values over 1

Steps to Reproduce

1. Create a Color Wheel with edge value 0
2. Create a Color Correct node and set the master gain to 2.0
3. Create another Color Correct node and set the highlight gain to 0
4. Go to the ranges tab and set the highlight range to x0.9 y0 and x1.1 y1

You will see an edge where the adjustment starts to darken values over 0.9, but will not increasingly darken values over 1, any rgb value over 1.1 should be black.
