effectcraft_project::cineon_log_to_lin does the log-to-linear conversion
for Interpret Footage > Cineon Settings and the Cineon Converter's Log to
Linear. Both raise the result to 1 / Gamma, so Gamma 1 gives linear light
and the same Gamma gives the same values in both. The converter's Linear
to Log, its Log to Log reference and the GPU shader use the same Gamma
scale, with a smallest Gamma of 0.01 / 1.7 (CINEON_MIN_GAMMA).
A test runs the converter at Gamma 1.7 (the default), 1 and 2.4 and
checks it against Cineon Settings at each code value.
