0.14.0-rc.1

This release refactors the implementation for serialization. All serializers now directly implement serde::Serializer instead of a custom trait. There are no breaking changes to the public interface, except for a polish of error messages.

• Performance improvements:
  • Avoid unncessary allocations in serialization
  • Reserve elements up front
• Improved error reporting in serialization:
  • The field and data type is now reported more consistently across builders
• More consistent handling of the serde data model in serialization:
  • Tuple variants, tuple structs can be used where tuples could be used
  • Treat newtype variants as transparents wrappers
  • Struct variants can be used where structs could be used
  • Support tuples, tuple, structs, tuple variants, bytes for FixedSizeList
  • Allow to serialize sequences for structs, similar to tuples
• Add options to consume the builder ArrayBuilder::into_arrow, ArrayBuilder::into_record_batch, ArrayBuilder::into_marrow that avoid additional allocations for metadata
