Nanolayer can't run on Python 3.12+

[BlastoiseBlue]

Nanolayer currently relies on invoke==2.0.0, which uses the imp module, which was removed from the standard library in Python 3.12.

Traceback (most recent call last):

ModuleNotFoundError: No module named 'imp'

Pinning invoke to at least 2.1.1, or relaxing the upper bound, should fix the issue.
