~ Updated Flow Architecture Document

~ Avoid using `/dev/null` for writing DEF files (it tries to create a temp file and fail)
~ PDK now has a default value of sky130A even outside the Makefile
~ PDK_ROOT now set automatically if Volare is installed
~ Upgrade to a newer version of OpenLane 2, which in turns uses `nix-eda`
~ Format nix packages using Alejandra
~ OpenROAD scripts now read liberty files before database files (they are linked together when the database is read)
~ Update Readme to remove Colab and add banner directing people to OpenLane 2
+ Added a new target to the Makefile, `make m`, which mounts the directory at the same path in the container as it is in the host
~ Changed Makefile to mount an empty folder where `install` is so there's less confusion
~ Updated banner per @shalan's recommendation
- Remove `make veryclean` which users may not use consciously and end up nuking their designs
~ Documentation all moved under `docs/source`, arranged hierarchically according to the table of contents
~ `Klayout` changed to `KLayout` in all logging messages
~ Readme rewritten to just be concise, parts of it isolated into standalone documentation
~ RTD builds no longer use conda (saves some time)
~ Fixed all broken links
ECO flow starts from checking the report generated in the route step. As PT commands are not supported by OL, we use a python script to check the report, insert buffers, and do the resize. Inside the ECO loop, the python script, cts and route step are called sequentially. The reports are generated each time, and the loop stops until no hold time violations are found.
The flow can be enabled using ECO_ENABLE =1.
More documentation and enhancements to come in the future.
