note: associated function defined here

Code is using usize in a few places, but since the size of usize is not fixed we should convert it to use u64/u32 depending on what is expected based on sqlite jsonb encoding spec.

Have created PR in my private fork with changes that compile against wasm, and tests pass too. Would you be interested in this?
