Detailed steps to reproduce the problem?

from bson import ObjectId
oid = ObjectId("0123                0011") # 24 characters
print(oid)                                 # outputs ObjectId('01230011')
ObjectId(str(oid))                         # raises TypeError

Definition of done: what must be done to consider the task complete?

bytes.fromhex skips whitespace so as long as the string is still a valid byte sequence without whitespace, it parses and sets the self.__id field. A possible fix would be to confirm that the bytes are still of length 12 after converting from the string.
