veTEC571 SDK problem

 INDI under Ubuntu 22.04.3

The new SDK which is shipped with the indi which ships with kstars 3.6.7, doesn't give even frames of any type. There's a shadow:

libomegonpro driver shipped with kstars stable 3.6.7:

The intense shadow is independent of camera orientation.

libomegonpro driver shipped with kstars stable 3.6.6:

All is as expected.

The new driver gives rise to a gradient, even with flat frames applied. No, this isn't light pollution:

After much head scratching, we discovered that the issue lay with the new driver. Reminiscences of ZWO. So, to get back to evenly lit camera frames which respond to flat frame division...

Roll back to the SDK/library library shipped with 3.6.6:

3.6.7 SDK: libomegonprocam.so.54.23231
3.6.6 SDK: libomegonprocam.so.54.22587

copy the 3.6.6 SDK to /usr/lib/x86_64-linux-gnu

remove the symlink libomegonprocam.so.54

then reform the link to point to the old SDK instead:

sudo ln -s libomegonprocam.so.54 libomegonprocam.so.54.22587

Not sure if there's a more elegant way to do this but basically I just changed the symbolic link to make /usr/lib/x86_64-linux-gnu look like this:

lrwxrwxrwx 1 root root 21 sep 30 20:04 libomegonprocam.so -> libomegonprocam.so.54
lrwxrwxrwx 1 root root 27 oct 17 11:42 libomegonprocam.so.54 -> libomegonprocam.so.54.22587
-rw-r--r-- 1 root root 21542824 oct 17 11:40 libomegonprocam.so.54.22587
-rw-r--r-- 1 root root 21637016 sep 30 20:04 libomegonprocam.so.54.23231

I've placed a copy of the 3.6.6 SDK here: drive.google.com/file/d/1TXvueJ8lPnXRUso.../view?usp=drive_link

**EDIT I've put a ready-to-go 54.23585 fix-everything library/sdk here: https://drive.google.com/file/d/1sMyPlkA0zXVGW00Fi-1FFn2RBgtnlf5H/view?usp=drive_link
