Rapidwright

**Release Notes:**
* Includes RWRoute - a full design timing driven router
* Moves online discussions and forum to GitHub Discussions
https://github.com/Xilinx/RapidWright/discussions (retiring Google Groups).
* Turns off Kryo Unsafe usage for Java 15 and above
* Better auto generation handling of readable EDIF files. Creates an
MD5 checksum for DCPs and unique directory for EDIFs to avoid stale EDIFs.
* Includes Python packaging files and adds the option to use local
development RapidWright build when RAPIDWRIGHT_PATH is set (see 267)
* Adds RapidWright relocation tools - the ability to relocate
implementations without using Modules/ModuleInsts.
* Includes a performance evaluation tool to leverage Vivado to
identify true fmax of a design.
* Improves PartNameTools to return integer values of available
resources of a part.
* Fixes Issues 259, 246, 73, 251, 190
- API Additions:
- com.xilinx.rapidwright.design.Design "public static boolean replaceEDIFinDCP(String dcpFileName, String edfFileName)"

**Release Notes:**
* Fixes ModuleInst anchor read issue when loading a RapidWright-generated DCP
* Adds correct macro expansion for BUFG and CFGLUT5 primitives
* For executable jars, the RapidWright default directory has been changed to ~/.local/share/RapidWright on Linux and %APPDATA%\RapidWright on Windows.
* Improvements in Utils and TileColumnPattern for URAM
* Adds dotty graph dump facilities for some logical and physical netlist classes
* Fixed an issue in PolynomialGenerator trying to create duplicate pins
* Various fixes around closing files and streams
* Includes fixes for 228, 238, 244
* Changes return type of Module "public RelocatableTileRectangle getBoundingBox()" from TileRectangle
- API Additions:
- com.xilinx.rapidwright.bitstream.Block "public boolean copyFrameData(Block block)"
- com.xilinx.rapidwright.bitstream.Frame "public boolean copyWords(Frame frame)"
- com.xilinx.rapidwright.design.Cell "public Cell createCell(EDIFHierCellInst inst, BEL bel)"
- com.xilinx.rapidwright.design.Net "public void unroutePin(SitePinInst p)"

**Release Notes:**
* Updates device models to the public set released in Vivado 2021.1
* Provides a cloud data file download-on-demand model. No longer need to
download large rapidwright_data.zip with each release. Speeds up
install and enables easier packaging/distribution of RapidWright.
* Adds support to automatically invoke Vivado to create a missing
EDIF file when loading a DCP (if a compatible Vivado is on user's PATH).
* Moves timing model files into git repo (out of data directory)
* Includes fixes for 180, 217

**Release Notes:**
* Several fixes for RapidWright API Lib:
- Resolves left over antennas from mishandled bi-directional PIPs
- Resolves issue in module instance creation due to AltPinmapping
cell names not being updated.
- Fixes range issue with BUFCE_ROW instance in Net.setBufferDelay()
- Fixes when anchor is null when writing out metadata for module
instance in DCP.
- Fixes issue when reloading a DCP with encrypted cells back into
RapidWright and EDN file paths not being propagated.
- Patch for dual output net situation where incorrect routing flags
caused Vivado to crash.
* Includes EDIFHier updates to reduce memory and improve runtime.
Avoids use of a String for hierarchical representation and instead
uses an array of EDIFCellInst
* Includes fixes for 193, 194 and partial for 206
* Includes JUnit tests

**Release Notes:**
* Updates Cap'n Proto Java Runtime from 0.1.4 to 0.1.7
* Updates Gradle wrapper to point to 7.1 (189)
* Updates the singleton Device map to have soft references. Allows
unused device objects to be garbage collected without having to call Device.releaseDeviceReferences().
* Includes a fix and some performance enhancements around module relocation.
* Interchange node discovery optimization (184)
* Fixes tile caching issue in GUI (185) and other device browser improvements (187)
* Workaround for Java 16 and Kryo library (191 - issue 190)
* Includes fixes for 183, 186
