v0.1.1

The first complete release of all four packages. 0.1.0's publish stopped partway, so AvroSharp.CodeGen 0.1.0 was never published; use 0.1.1. The code is the same as 0.1.0.

Fixed

• Releasing: AvroSharp.Generators no longer produces a symbol package. It had no .pdb in it, since the generator ships under analyzers/, and nuget.org's rejection stopped the 0.1.0 publish before AvroSharp.CodeGen. The generator's PDB is embedded in its DLL instead. The release workflow now pushes each package separately and checks, while packing, that every symbol package contains a PDB.
