Camera profile for Pentax K-1 MKII overexposure

[newmikey202]

Describe the bug

The exposure setting in the builtin camera-specific style for the Pentax K-1 MKII results in the exposure slider set to 1.5 which is objectively too high. The dtstyle for the slightly older Pentax K-1 gives the desired outcome which is +0.5 Ev

The histogram confirms the overexposure.

Steps to reproduce

Load Pentax PEF files for K-1 Mark II and apply or auto-apply via the lua script the dtstyle preset for the specific camera model.

Expected behavior

Set the Ev value in the exposure module to +0.5 Ev
