Decomp in Ghidra-Haskell

[mpdairy]

I don't really know how the decomp view works through the Ghidra API, but it could be really useful to have access to Ghidra's decompilation output. We also want to make sure that we can associate parts of the decomp with addresses of binary level instructions. Ghidra does this in the UI, like when you click on something in the decomp view, it highlights the underlying instruction in the disassembly view.
