Remove fujifilm_dynamic_range script

[horazont]

The script is superseded by darktable@086ec9c3480b297324a21e4a5012759b679e92f7.

Not sure if it's appropriate to remove this, but I thought I'd point it out / propose to remove it anyway. Feel free to close if it doesn't make sense.

I'll target it for late January 2026. That will give users a month to test and make sure the PR works for them.

Thanks

SGTM, thanks!
