Please excuse the last commit lacking a changelog. + PDK installation uses Volare, transparently to the user: all they have to do is type "make", where it will get OpenLane and the PDK + CI now uses Volare to either **get** or **build** the PDK (if not found), which speeds up the fastest test set by around 60%. + Added rudimentary dependency installation instructions. + pyyaml folded into the repo, so users without pip can still run issue surveys ~ Open PDKs updated: Parasitics are now extracted using a rules file based on [spef-extractor](https://github.com/Cloud-V/spef-extractor) as a ***temporary*** measure ~ Issue survey no longer checks for click and pyyaml: a venv is used in those scenarios. ~ OpenLane build no longer uses the host filesystem as an intermediary, instead using a templated dockerfile with an N-stage build for N tools, saving IO operations (40% improvement measured) ~ Old PDK targets renamed to build-pdk-conda, includes SRAM by default ~ Replaced python3 ./env.py issue-survey with `make survey` - Removed Fault from documentation (until I get the chance to work on it)
