/* fast_strtof
  
  
    This is a subset (just float fast_strtof() ) of  fast_atof by Peter Miller 23/1/2020
    See below for license information.
    
	 The code should be robust to anything thrown at it (lots of leading of trailing zeros, extremely large numbers of digits, etc ).
	 As well as floating point numbers this also accepts NAN and INF (case does not matter).
