Verify Proof without leaves, just with proof, root and leaf

Describe what you expect! (Example)

I want Merkly to work like this:

import merkly

proof, leaf = get_data_from_api()

root = "0xe35e6e14fdf91ecc6adfb74856bcd8a2c22544bd10bded94f2a9fecc77cf630b"

result = merkly.verify_proof(proof, leaf, root)

assert result == True
