Description
Introduce APIs for reading and writing 7z (.7z) archives.
7z is one of the most widely used archive formats, offering high compression ratios and support for multiple compression methods. .NET currently has no built-in support for it, requiring third-party libraries.
**Dependencies**
- Raw LZMA1/LZMA2 encoder and decoder (#126053) : provides the underlying compression/decompression
