[Bug] Can't delete messages

[AlexXanderGrib]

Conditions

1. Client logged in as bot
2. Bot has full permissions in the chat
3. Message exists

Code

td.invoke({
  _: 'deleteMessages',
  chat_id: -1001111111111,
  message_ids: [2219055],
  revoke: true
});

Error

({
  _: 'error',
  message: 'Invalid message identifier',
  code: 400
});

Actually, message ids in Bot API and TDLib are different. They are skewed by 20 bytes.

So here is the code to solve this

function tdMessageId(botApiMessageId) {
  return Number(BigInt(botApiMessageId) << 20n);
}

function botApiMessageId(tdMessageId) {
  return Number(BigInt(tdMessageId) >> 20n);
}

Conversion to BigInt is required cause bitwise operations truncate any integer stored in Number to just 32 bytes
