Add Binary test to account for when string has a space
Add Binary test to account for when string has a space

* Right now in `test_invalid_binary_numbers_raise_an_error` there is no
  check for if the string passed in has a space and then invalid binary.
  The problem with this is that values that should be failing can pass
  in someones code. For Example if someone was to use the regex
  `/\b[01]+\b/` to validate the binary and the binary passed in was "001
  yolo" it would still match 001 and not raise an error. This commit
  just adds in the case where `"001 yolo"` is passed in to make sure it
  raises an argument error still.
