Cannot get current processor architecture in .NET 9

[hyperlapse122]

Describe the bug AssemblyName.ProcessorArchitecture was deprecated and always returns ProcessorArchitecture.MSIL in .NET 9. Due to this change, Platform.Current always returns unknown architecture on Windows x64 (It worked on .NET 8). (please refer to this code using AssemblyName.ProcessorArchitecture

There is RuntimeInformation.ProcessArchitecture and RuntimeInformation.OSArchitecture but I don't know if it can be used for it.

To Reproduce

• Create an empty console application with fo-dicom and fo-dicom.Codecs, and try encode / decode DICOM image.

Environment:

• OS: Windows 11 24H2 (10.0.26100.2314)
• fo-dicom nuget package version: 5.1.4
• fo-dicom.Codecs nuget package version: 5.15.2
