py/parsenum: Use int instead of mp_int_t for parsing float exponent. 

There is no need to use the mp_int_t type which may be 64-bits wide, there
is enough bit-width in a normal int to parse reasonable exponents.  Using
int helps to reduce code size for 64-bit ports, especially nan-boxing
builds.  (Similarly for the "dig" variable which is now an unsigned int.)
