First Psalm v7 beta!

Announcing the first public beta of Psalm v7!

Psalm v7 brings huge performance improvements to security analysis, up to 10x thanks to a full refactoring of both the internal representation of taints, and optimization of the graph resolution logic.

It also brings performance improvements to dead code analysis, and fixes for list types.

Even more performance improvements and new features will be released soon!
