support log transaction from iframe plugin

[drafish]

I'm developing an iframe plugin for xinghuo bif, and I want to send a transaction log, and I got some issues.

Here is the first one.

Check the code here - https://github.com/ethereum/remix-project/blob/master/libs/remix-ui/terminal/src/lib/components/Context.tsx#L19

provider will be missing if the transaction log is called from iframe plugin.

Here is another one.

The decoded input does not convert correctly when it's BigNumber.

Here is the correct convert result.

BigNumber will turn to a ordinary object if it's passed through postMessage.

I don't think we should do that here.
What are the input parameters?
You could have a default behavior when provider is not present.

Here is an example of input parameters. @yann300

{
  type: 'knownTransaction',
  value: {
    tx: {
      hash: resp.detail.hash,
      isCall: false,
      blockNumber: resp.detail.ledger_seq,
      transactionCost: resp.detail.actual_fee,
      from: resp.detail.transaction.source_address,
      to: null,
      transactionIndex: resp.detail.transaction.nonce,
    },
    receipt: { status: '0x1', contractAddress: resp.detail.contractAddress },
    resolvedData: {
      contractName: selectedContract.name,
      to: null,
      fn: '(constructor)',
      params: eventsDecoder._decodeInputParams(getinputParameters(data.dataHex.replace(data.contractBytecode, '')), txHelper.getConstructorInterface(selectedContract.abi)),
      contractAddress: resp.detail.contractAddress,
    },
    logs: logs,
  },
  provider: 'bif',
}
