Ghidra script that finds jumptable targets for PS3 jumptables (generated for C 'switch'es) and adds refs to their indirect jump instruction

FindJumptableTargets.py

# Finds jumptable targets for PS3 jumptables (generated for C 'switch'es) and adds
# refs to the indirect jump instruction so that decompilation for the cases is present
# (instead of Ghidra complaining with an error in the switch as it often does).
# Select the block with the address offsets before running (first mark them all as
# addresses with `P` and `[`).
# After you run this you'll probably want to select the indirect jump instruction
# (usually `bctr`) and run the SwitchOverride.java script.
