Async work

[adamhathcock]

Using AI, I'm converting things to have asynchronous overloads as well as tests for them.

Here's what I think I need to finish:

Stream Classes Needing Async Overloads

Summary

• 36 classes need ReadAsync overload
• 17 classes need WriteAsync overload
• 37 total classes need async overloads (16 need both)

Validation Notes

This list excludes Stream classes where the Write method throws NotSupportedException or NotImplementedException, as these are read-only streams that don't need WriteAsync overloads.
