#1820 Add support for decompiling standalone ABC files
It would be very useful if JPEXS could decompile '.abc' file (containing ABC bytecode). Some tools like RABCDAsm (https://github.com/CyberShadow/RABCDAsm) work with these files. Currently, it's necessary to wrap ABC bytecode in a 'DoAbc2' tag inside an SWF for JPEXS to compile it.
