Don't work with multi threads and jupyter

[lucasccampos]

running Multicall in main thread works great, but running the function twice in another thread is going to throw an error

"RuntimeError: Timeout context manager should be used inside a task"

and when using Multicall with jupyter, u get this error

latest multicall works with jupyter if you install: https://github.com/erdewit/nest_asyncio

in the jupyter cell add:

import nest_asyncio nest_asyncio.apply()

multithread issue is fixed if you use web3>=5.31.3

Jupyter issue is related to jupyter event loop and solution has been shared above. Closing.
