10.2.1

This patch release includes a couple of bug fixes:

• The C# code generator now emits DateOnly and TimeOnly types for date and time logical types (#298, h/t @xontab).

• When inspecting a type for members that match enum symbols or record fields, the serde builders no longer count constructors, events, nested, etc. as colliding names (#299). If names collide, builders throw more informative exceptions.
