=head2 random_bigint
Returns a random 63 bits L<Math::BigInt>. Some architectures do not support
native 64 bit integers, but that is what DataDog expects.
NOTE: special care needs to be taken when rendering to JSON, as the GO language
is not forgiving for double qouted values when using big numbers.
Use C<<JSON->allow_bignum>>.
