BigInt can't support u128 or i128

[lastmjs]

Hi, I believe that a JavaScript bigint should be able to handle Rust u128 or i128 values, but BigInt only has from_u64 and from_i64.

Does rquickjs have a way to safely and precisely convert u128 or i128 values to BigInt? If not, I feel that it should.

Unfortunately QuickJS itself doesn't have a way to covert between u128 and it's BigInt type which is why rquickjs also doesn't support it.
Support for this would require support for it in QuickJS.
