v0.2.1

• Updated packaging for LightningSimV2, which now supplants the original lightningsim conda package
  • Note that classic LightningSim and LightningSimV2 can no longer be installed side-by-side. If you need this functionality, please use v0.2.0 or revert 79cb0a6.
• Fixed several linker issues to try to be more generic across environments and Vitis HLS versions
• Improved minor quality-of-life features (e.g., smarter automatic port selection for web server)
