📄 Description

Related to https://github.com/adamhathcock/sharpcompress/issues/992

This pull request adds asynchronous read and write support to the ADC and BZip2 compression streams, enabling non-blocking operations and cancellation support. It introduces new async methods and refactors existing classes to handle asynchronous workflows, improving integration with modern .NET applications. Comprehensive tests are also added to verify the correctness and robustness of the new async features.

ADC Compression/Decompression Enhancements

  • Added AdcDecompressResult class to encapsulate results of ADC decompression, including bytes read and output buffer.
  • Implemented DecompressAsync methods in ADCBase.cs for asynchronous decompression of byte arrays and streams, supporting cancellation tokens and buffer pooling.
  • Added ReadAsync method to ADCStream.cs to support async reading and decompression with cancellation support.

BZip2 Compression/Decompression Enhancements

  • Added async read and write methods to BZip2Stream.cs, including overloads for both byte[] and Memory<byte> buffers, supporting cancellation tokens.
  • Implemented async read in CBZip2InputStream.cs and async write in CBZip2OutputStream.cs, both with cancellation support. [1] [2]

Test Coverage

  • Added AdcAsyncTest.cs to test asynchronous ADC decompression, chunked reads, and cancellation scenarios.
  • Added BZip2StreamAsyncTests.cs to verify async compression/decompression, multiple async writes, cancellation, and large data handling for BZip2 streams.
