Installing through setup.py fails

[nicsalv]

Trying to install this package by executing setup.py always fails with this error error: package directory 'steerable_pytorch' does not exist.
I got it to work by replacing steerable_pytorch at

PyTorchSteerablePyramid/setup.py

Line 13 in e54981e

packages=['steerable_pytorch'],

with steerable.

@nicsalv @tomrunia I've made a pull request to fix this in the main branch.
