Allow outputs to have fungible tokens and NFTs

[SayoshiNakamario]

In TransactionBuilderHelper.ts the prepareTransactionOutputs() helper function which buildTransaction() calls sets any outputs with an NFT on them to 0 fungible tokens. If an NFT output did also have tokens on it (e.g. BadgerNFT + badgercoins) then the fungible tokens would be burned, or if interacting with a contract that enforced tokenAmount the wallet would be unable to interact with the contract.

 // If there's a token field
      if (output.token) {
        // If the token has NFT data, we enforce a zero fungible amount
        if (output.token.nft) {
          return {
            ...baseOutput,
            // Always zero for NFT
            token: {
              amount: BigInt(0),
