Error on import cadquery with new install without explicitly specifying occt version

[lorenzncode]

Install command: mamba install -c conda-forge cadquery

It looks like this issue is due to new OCCT 7.7.1.

master has a pin for occt after merging #1293

Checked today, healthy again under windows.

The issue seems to be still present with Linux:

conda list "cadquery|ocp|occt"
# packages in environment at /home/bruno/.conda/envs/cadquery:
#
# Name                    Version                   Build  Channel
cadquery                  master                    py3.9    cadquery
occt                      7.7.1                h6cf717c_0    conda-forge
ocp                       7.7.0.0          py39h5d0cb9e_1    conda-forge

and I get the mportError: /home/bruno/.conda/envs/cadquery/lib/python3.9/site-packages/OCP.cpython-39-x86_64-linux-gnu.so: undefined symbol: _ZN20DE_ConfigurationNode10UpdateLoadEv error
When I try to force-reinstall cadquery=master with conda I get

CondaHTTPError: HTTP 404 NOT FOUND for url <https://conda.anaconda.org/cadquery/linux-64/cadquery-master-py3.9.tar.bz2>

@bragostin, There was a problem with the conda upload after the latest commit yesterday.

As a workaround, if you do not require the latest dev build, you can install the release version 2.2.0 (conda or mamba):
mamba install -c conda-forge cadquery=2.2.0 occt=7.7.0
or
mamba install -c conda-forge cadquery occt=7.7.0

The installation instructions for the latest release have also been updated in #1305.
