Refactor and Add accessor protocol support to stats/base/mean #5629

[apfossdev]

Refactor the mean function to add support for the accessor protocol. This change ensures that the function can handle array-like objects with custom accessors, improving flexibility and compatibility with various data structures.

• Refactor mean function in main.js to delegate to ndarray.js
• Update ndarray.js to handle accessor protocol
• Add tests for accessor protocol support
• Fix JSDoc comments and examples for accuracy

Fixes: #5629

Hello! 👋

I've noticed that your commit doesn't contain the expected YAML metadata blocks. This typically happens when your development environment isn't properly set up with the stdlib git hooks.

Here's how to fix this:

1. Install project dependencies (run this command in the top-level directory of the project):

   make install

2. Initialize the development environment (this sets up the Git hooks among other things):

   make init

If you're still having issues, please check our development guide for more information.

Thank you for your contribution!
