Re-Revert "Merge #101508: libraw: 0.20.0 -> 0.20.2"
This reverts commit c778945806.

I believe this is exactly what brings the staging branch into
the right shape after the last merge from master (through staging-next);
otherwise part of staging changes would be lost
(due to being already reachable from master but reverted).
