Print more fit statistics, as well as a more standard equation form.
...
Also print the code in pseudo code rather than Rust.
Also a few tweaks to other areas of the code.

Fix stupid bug in test image export.
...
This was correct the last time I exported the image (it was
introduced in the refactor a while ago), and the bug was only in
the export part, not the reading part. So all of the LUT
extraction we've done has been correct, thank goodness.

Estimate the linear slope with error minimization.
...
This works better than doing it analytically because of
floating point math, and give significantly lower error on
the fitted curve.
