LinqBenchmarks

Benchmarks comparing the performance of LINQ against for/foreach loops and the following libraries:

• Faslinq
• Cistern.ValueLinq
• JM.LinqFaster
• LinqFasterer
• LinqAF
• SpanLinq
• StructLinq
• NetFabric.Hyperlinq
• System.Linq.Async

NOTE: Removed LinqOptimizer and Streams from the benchmarks as they are slower than LINQ on every benchmark.
