Create Uint128 out of 2 Uint64

[johanmazel]

Could you add this feature ? If you cannot, I can probably code this and try a pull request.

Hi Johan

Would conversions from the other uint types to uint128 be enough? Then you could implement it with something like

let uint128_of_two_uint64 x y =
  let (||) = Uint128.logor in
  let (<<) = Uint128.shift_left in
  let u128 = Uint128.of_uint64 in
  (u128 x << 64) || u128 y

The Uint128.of_uint64 function doesn't exist, but it would be trivial to add.

Cheers, Andre

Yes, that would be perfect. Could you also add a uint64_of_two_uint32 function ? And maybe a uint128_of_four_uint32 function ?
