When using many reflection probes with different subdivisions
it can happen that the reflection probe uses texture space that
is already been allocated for another probe.
The cause for that is that negative shift operations result into
undefined behavior, this was fixed previously by clamping the
number of bit shifts to perform, but ignoring to shift into the
other direction
This change also includes `ProbeLocationFinder.print_debug`
for future debugging.
