Proposal for updated Filmic curve parameterisation in Darktable

I often wonder if some of the feelings around filmic come from attempting to use it on every image and expecting it to do more than it is designed to do. Call it maybe over reliance on filmic. By placing filmic in that role maybe this is where some of the problem might lie.

Well, @s7habo uses it all the time, and he gets great results with it:

For me, filmic is always embedded in the processing steps and serves mainly as an aid in dealing with different dynamic ranges of photos one is confronted with as a photographer.
