Updating issues, licensing, Readme

[FeliciaG]

Fixes #10 , #11

Many of the hardcoded paths in issue #11 depend on user setup of other tools. These paths have just been commented to indicate the user needs to update to be compliant with their directory setup.

Readme has been updated to reference new documentation and refer to BAG as Berkeley Analog Generator

Tests are failing because bag_prim.cdl and bag_prim.scs are missing the copyright headers. However, these files are generated by scripts, so this test should be removed.

This branch has conflicts that must be resolved

Changes generally look okay. Will add comments when the conflict is resolved.

@FeliciaG Could you do a rebase rather than a merge?

[mithro]

Looks like you still did a merge rather than a rebase....

You want to do something like;

git remote add upstream git@github.com:google/skywater-pdk-libs-sky130_bag3_pr.git
git fetch upstream
git rebase --interactive upstream/master
