Description

What is the purpose of this pull request?

This pull request introduces a new stats/strided package, dmadsorted, which computes the median absolute deviation (MAD) for sorted double-precision floating-point strided arrays.

The median absolute deviation is a robust measure of statistical dispersion that is less sensitive to outliers than variance or standard deviation. Adding dmadsorted extends the existing family of strided statistical functions (e.g., dmediansorted) and provides a commonly used robust statistic in a performance-oriented, strided form.

This PR includes:

• A JavaScript implementation following existing stats/strided/*sorted conventions
• A corresponding C API implementation
• Comprehensive JavaScript tests
• C benchmarks to evaluate performance
• Usage examples and documentation (README and REPL help)
