Chud Pi and "raw" output (cino hilliard)

Much quicker would be write yourself a pair of 
mpf_out_raw and mpf_in_raw functions. For output just
dummy up an mpz_t pointing to the mpf, write the size
and exponent, then mpz_out_raw.

The input process is similarly simple.

No radix conversion whatsoever, hence virtually nil
overheads.
