leading space to the expression is breaking

[sreeanthrds]

When we add one or more spaces at the starting of the expression string, the code is breaking. This is syntactically valid. No idea why is it failing.

from baron import parse, dumps
source_code=' 1+2 '
parse(source_code)

Pars ingError: Error, got an unexpected token SPACE here:

1 <---- here

The token SPACE should be one of those: ASSERT, AT, BACKQUOTE, BINARY, BINARY_RAW_STRING, BINARY_STRING, BREAK, CLASS, COMMENT, COMPLEX, CONTINUE, DEF, DEL, ELLIPSIS, ENDL, ENDMARKER, FLOAT, FLOAT_EXPONANT, FLOAT_EXPONANT_COMPLEX, FOR, FROM, GLOBAL, HEXA, IF, IMPORT, INT, INTERPOLATED_RAW_STRING, INTERPOLATED_STRING, LAMBDA, LEFT_BRACKET, LEFT_PARENTHESIS, LEFT_SQUARE_BRACKET, LONG, MINUS, NAME, NONLOCAL, NOT, OCTA, PASS, PLUS, RAISE, RAW_STRING, RETURN, STAR, STRING, TILDE, TRY, UNICODE_RAW_STRING, UNICODE_STRING, WHILE, WITH, YIELD

Baron has failed to parse this input. If this is valid python code (and by that I mean that the python binary successfully parse this code without any syntax error) (also consider that python does not yet parse python 3 code integrally) it would be kind if you can extract a snippet of your code that make Baron fails and open a bug here: https://github.com/PyCQA/baron/issues

Sorry for the inconvenience.
