Insert co_posonlyargcount into args

[TabulateJarl8]

Until this is done you get this error:

Traceback (most recent call last):
  File "/home/tabulate/snek.py", line 4, in <module>
    def main():
  File "/home/tabulate/.local/lib/python3.9/site-packages/goto.py", line 240, in with_goto
    _patch_code(func_or_code.__code__),
  File "/home/tabulate/.local/lib/python3.9/site-packages/goto.py", line 231, in _patch_code
    return _make_code(code, _array_to_bytes(buf))
  File "/home/tabulate/.local/lib/python3.9/site-packages/goto.py", line 58, in _make_code
    return types.CodeType(*args)
TypeError: an integer is required (got type bytes)

This is because types.CodeType started requiring another argument, posonlyargcount. If you use the inspect module, you can see the arguments needed for this function.

>>> import types
>>> import inspect
>>> print(inspect.getdoc(types.CodeType))
code(argcount, posonlyargcount, kwonlyargcount, nlocals, stacksize,
      flags, codestring, constants, names, varnames, filename, name,
      firstlineno, lnotab[, freevars[, cellvars]])

Create a code object.  Not for the faint of heart.

I got this error using Python 3.9, and after adding this it works again

Alternatively, this works too:

def _make_code(code, codestring):
    return code.replace(co_code=codestring)

[TabulateJarl8]

Closing because of #22

[wdyyoij]

code.replace(co_code=codestring)

u r so fking awesome!
