added python 3.10 support

[ghost]

added "temporary support" for python 3.10, however some of the newer opcodes are not in bytes/python_310.map to prevent conflict with the undeclared pycdc opcodes , however im working on them, any suggestions on how i should add them to ASTree would be appreciated thanks!

You can add the new opcodes to bytecode_ops.inl. The order doesn't matter much, except that the opcodes with no arg (OPCODE()) need to be before those with an arg (OPCODE_A()). I usually just add new opcodes to the end of these two lists for simplicity.
