ZIO Files

This release of ZIO brings several new features, performance optimizations and bug fixes!

Highlights

1. New ZIO.fromFunction and ZIO.fromFunctionZIO methods that allow extracting multiple values from the environment in a single effect (#9819 & [#9782])
2. (Scala 3 only) New provideSomeAuto method for ZIO and Spec, which works similarly to provideSome but without having to provide the environment remainder explicitly.
3. New mapChunksEither and mapEitherChunked methods on ZPipeline give users more options in short-cutting errors when processing streams
