Struct byte values typed as Uint8Array, but are actually number[]

[joe-p]

Subject of the issue

For structs in state, the client generator will generate a type like:

Your environment

Steps to reproduce

1. Run client generator with struct that has bytes in it

2. See generated type

export type ClaimedInfo = {
  txnId: Uint8Array
}

3. Retrieve that value

        const claimedInfo = await appClient.state.box.claimedMap.value({
                    tokenDropId: dropId,
                    address: claimAccounts[i].addr.toString(),
                } as AddressClaimKey)

Expected behaviour

claimedInfo.txnId is Uint8Array

Actual behaviour

claimedInfo.txnId is number[]
