Telethon: Unable to join private channel using telegram's new invite hash format.

It is no longer possible to join a private channel via their invite links/hashes. I will provide a proof of concept of the failure and the corresponding error log below.

import asyncio
from telethon.sync import TelegramClient
from telethon.tl.functions.messages import ImportChatInviteRequest

async def main():
    tg_hash = '<enter_invite_hash_here>'
    async with TelegramClient('anon', <enter_API_id_here>, '<enter_API_hash_here>') as client:
        chat_invite = await client(ImportChatInviteRequest(tg_hash))
asyncio.run(main())

File "test.py", line 27, in main
    chat_invite = await client(ImportChatInviteRequest(tg_hash))
  File "/home/test/.local/lib/python3.7/site-packages/telethon/client/users.py", line 30, in __call__
    return await self._call(self._sender, request, ordered=ordered)
  File "/home/test/.local/lib/python3.7/site-packages/telethon/client/users.py", line 79, in _call
    result = await future
telethon.errors.rpcerrorlist.InviteHashExpiredError: The chat the user tried to join has expired and is not valid anymore (caused by ImportChatInviteRequest)

Raises InviteHashExpiredError even when:

• After stripping/remove ‘+’ character from the telegram invite hash string (example: hlQ3QhNi6q05ZDIx).
• Providing full telegram invite hash string (example: +hlQ3QhNi6q05ZDIx
• Providing full telegram invite hash string with link/t.me domain (example: https://t.me/+hlQ3QhNi6q05ZDIx)
