cleaner alternative syntax for python ctypes structures, allowing autocompletion

binattrs.py

def binattrs(cls):
    cls._fields_ = tuple(cls.__annotations__.items())
    return cls

main.py

import ctypes as ct
from binattrs import binattrs

@binattrs
class Hello(ct.Structure):
    field1: ct.c_uint16
    field2: ct.c_uint16

h = Hello.from_buffer_copy(bytes([0x01, 0x02, 0x03, 0x04]))

print(h.field1, h.field2)
