Catch exception when there is memory overlap

[kost-div]

Currently, when there is memory overlap in memory ranges, it fails with following exception:

Loading SVD file...
        Done!
Generating memory regions...
Traceback (most recent call last):
  File "/opt/ghidra-scripts/SVD-Loader-Ghidra/SVD-Loader.py", line 113, in <module>
    t = currentProgram.memory.createUninitializedBlock(r.name, addr, length, False)

SVD-Loader.py> Finished!

So, clearly general exception block do not catch specific exception for memory overlap.

Fix catch correct exception and displays the following:

  Loading SVD file...
	Done!
Generating memory regions...
	Failed to generate due to conflict in memory block for: CRC
('\t', ghidra.program.model.mem.MemoryConflictException: Part of range (40023000, 400233ff) already exists in memory.)

Hope it helps and thanks for the SVD loader!
