rename short identifiers

[3052]

is it possible to correct short variable names? for example with JADX, it has this option:

 --deobf                             - activate deobfuscation

which will turn short variables such as a into a1234 or something, for easier searching

found another tool that works:

synchrony deobfuscate --rename obf.js
