addition of bn_out_hex function.

[dbdeadka]

Hi, Evan!

Thank you so much for the good extension.
I want to offer some additional function for output bignum value in hex.

t=# create table t(a bignum, b bignum);
CREATE TABLE
t=# insert into t values(bn_in_hex('ffffffffffffffff'),bn_in_hex('ffffffffffffffff'));
INSERT 0 1
t=# select bn_out_hex((a+1) * (b+1)) from t;
             bn_out_hex
------------------------------------
 0100000000000000000000000000000000
(1 row)

In awaiting for your feedback,
Sincerely,
