int(x) does not work for strings with preceding/trailing whitespace

[nielstron]

Describe the bug The function int(x) in the python standard lib implicitly strips the invoked string before converting it to an integer. OpShin does not currently do this, breaking the semantic equivalence with python

Example

int("0\n") 
   -> 0 (in Python)
   -> error (in opshin)
