Rapidwright

**Release Notes:**
* Adds IOBank and IOStandard data to Package objects in device model
to match Vivado Tcl capabilities.
* Allows Ports to have multiple pins (see 156 for details)
* Fix for Issues 161, 159, 61
* Minor DCP format changes for improved Versal support
* Gradle improvements (see 165 for details) that adds three tasks:
1) 'run' - a top level application to run a sub application in RapidWright directly
2) 'installDist' - Creates a distribution of all RapidWright dependant code with convenience startup scripts
3) 'distZip'/'distTar' - Creates a zipped/tar'd distribution
* Allow ports to have multiple pins
* A few other minor changes, please see commit log for details

results from a design on a per-module basis.
* Resolves Issue 127 - Duplicate PIPs from Tile.getPIPs()
* Fixes an issue related to not traversing routethrus when searching for site pins
* Fixes an issue in UltraScale clock routing getting stuck in a loop when routing to LCBs.
* Fix for missing portInst on FF routethrus
* Fixes missing BRAM site pins with multiple mappings

**Release Notes:**
* Adds a set of bitstream manipulation APIs
* Adds part name normalization (see pull request 120)
* Bug fix for migrateCellAndSubCells() (see pull request 116)
* Fixes an NPE on getSitePinFromLogicalPin()
* Fixes support for BUFCE_ROW on Net.{get,set}BufferDelay()

**Release Notes:**
* Adds initial support for Versal devices (Vivado 2020.2 compatibility)
* Augments PackagePin metadata to more closely provide available properties found in Vivado.
* To support interchange: DesignTools.getInvertiblePinMap() which provides a map for a unisim to
denote which pins are invertible by which parameter names
* The Part class has been augmented with a set of new methods that contain basic resources
for a particular part that are reported in Vivado with the 'report_property' command,
these methods include: getAvailableIobs(), getBlockRams(), getDsp(), getFlipflops(),
getGbTransceivers(), getLutElements(), p.getMmcm() and p.getUltraRams()
