More intelligent variable renaming with JsxBlind deobfuscation

[AngeloD2022]

In the deobfuscator's current state, it renames symbols with names that have characters that are not valid. It achieves this by renaming an affected variable from Unicode weirdness to, for example, symbol_34. Ideally, we can look at the values assigned to any given variable and rename it using an automatically generated brief description of its assigned contents. We could also take into consideration how the variable is used–say a loop iteration variable for example.
