Start rewrite serde serialization tests

Add a `read_text` implementation for async readers

This adds a read_text_into_async method for Readers which allows writing the content in between nested tags to an arbitrary AsyncWriter , analogous to Reader::read_text and NsReader::read_text respectively.
