调研方向

首先阅读现有的 BZip2OutputStream，并将其同步写入和释放行为与此处描述的异步流要求进行比较。检查项目对异步流 API 的约定，并确定所需的贡献和测试；当异步 BZip2 输出流能够支持 ASP.NET Core 响应流式传输，且其主要操作不依赖同步 I/O 时，即视为完成。

描述

bzip2 enhancement
Is your feature request related to a problem? Please describe.

I want to stream BZip2-compressed data from a result handler in an ASP.NET Core web app. The ASP.NET Core response stream only supports async operations. I found that BZip2OutputStream is inherently synchronous, so I copied it into my project and created BZip2AsyncOutputStream by means of straightforwardly replacing all calls to synchronously output bytes with async calls instead. A couple of cases required async-over-sync (explicit .Wait), since e.g. disposing the stream results in synchronous .Write and .Flush calls, but in the main operation it's all async. It seems to work. No idea on the impact on efficiency.

Would there be any interest in a contribution of this class?

Describe the solution you'd like

I'd like to make a PR that adds BZip2AsyncOutputStream to SharpZipLib so that other people who, like me, want to stream BZip2-compressed data in contexts that don't support synchronous I/O have an option. But I don't want to make a PR if it is unwelcome. :-)

Describe alternatives you've considered

There aren't really any alternatives, as I understand it. Async code simply requires you to be async up and down the call stack.
