Readme sais it only supports int[] for .NET 7 and later

[jonadv]

can somebody tell me what "it" in that first line refers to?

I can only read it in a way that

• SIMD is only available from .NET 7 onwards but also
• SIMD in .NET 7 (and later) only works for int[]

so the whole package is only for int[] and will not have any effect on for example double[]

This refers to the range of SIMD support provided by LINQ in .NET.
