bw2analyzer v2 imports _currently_ obsolete classes from bw2calc

[tngTUDOR]

An install of brightway25 1.0, using conda on a clean python 3.9 environment with:

conda install -y -q -c conda-forge -c cmutel -c haasad brightway25

will produce import error on basic imports suggested at the homepage of the brightway25 repo as shown below. It seems that some classes are not published anymore in bw2calc.

Python 3.9.5 (default, Jun  4 2021, 12:28:51) 
Type 'copyright', 'credits' or 'license' for more information
