Look into automatic deobfuscation

[holly-hacker]

I should investigate whether it is possible to optimize/deobfuscate the IL that is fed into the decompiler, to allow for cleaner decompilation output.

Preferably, the following optimizations should take place:

• Evaluating pure operations (assuming they cant be hooked) such as Math.* or sizeof
• Eliminating dead branches. This would include switch statements.

For more advanced implementations, it could also look at existing methods in the binary and check if they are pure. The optimization/deobfuscation logic should be moved to another project/repo, so it can be developed independently.

This may require a custom decompiler, in which case I should look into just copying the existing implementation (since dnSpy is no longer being developed).
