Benchmarking ways of checking if some small or large string is numeric

In this demo, i m using BenchmarkDotNet library in order to benchmark various ways of checking if some small or large string is numeric.

1️⃣ SmallNumericBench : a bench for small numbers (size less than or equal to 19 characters)

2️⃣ LargeNumericBench : a bench for large numbers (size greater than or equal to 20 characters)
