List index out of range: version 84

[Puyodead1]

I get the following error when trying to disassemble an android bundle using hermes bytecode version 84:

[*] Disassemble 'index.android.bundle' to 'out' path
[*] Hermes Bytecode [ Source Hash: d47dd92ea0ad2ab0ad46438a7f6f4a2ee383dbf5, HBC Version: 84 ]

Same problem here - To add a bit of debugging info: IndexError: list index out of range form line 33 in hbc/hbc84/translator.py. with: bc[i] -> 271 and len(opcode_mapper) -> 201

I'm not sure if the opcode integer is parsed wrong when being read from the binary, or if the 84'er version has many more opcodes, that als are missing.
