[PATCH 0/7] MR8837: opcservices: Add basic support for reading OPC packages.
This MR introduces an initial implementation for `ReadPackageFromStream` in order to be able to decompress/read OPC packages, and enumerate their parts. This is for supporting AppX packages, which themselves are OPC packages as well. As such, the code does not implement support for reading relationships or interleaved archives, as AppX does not support either (`APPX_E_RELATIONSHIPS_NOT_ALLOWED`, `APPX_E_INTERLEAVING_NOT_ALLOWED`). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8837

Why do we need this? Implementing `Windows.Management.Deployment.PackageManager` requires support for reading appx/msix files. As we already had opcservices, I thought it'd be better to use `IOpcPackage/PartSet` to do that, instead of having separate ZIP + inflate code.
