Title: dt-curve-tool OpenMP conversion

Two loops were good candidates for an easy OpenMP conversion.

powf is now 85% of the perf profile. Unless we come up w/ parallelization in dt-curve-tool-helper (as convert, dcraw and so on are so slow) or a powf optimized replacement, i see no easy gain now.
