[RFC]: Add C implementation for @stdlib/stats/base/dists/planck/pmf

[yuvi-mittal]

Description

This RFC proposes adding a C implementation, including a Node.js native addon, C benchmarks, and C examples, for the @stdlib/stats/base/dists/planck/pmf package.

When adding support, the following tasks should be completed:

1. A C source implementation should be added to a src folder within the package's directory.
2. A native add-on interface should be added in order to call the C implementation from JavaScript.
3. A JavaScript file should be added to the lib folder to allow benchmarking and unit testing the native implementation from JavaScript.
4. A new test file should be created which includes unit tests testing against expected behavior.
5. C benchmarks should be added which measure performance for the C source implementation.
6. A file containing C examples should be added to demonstrate example usage.
7. JavaScript benchmarks should be added which measure performance for the native add-on.
8. Build and configuration files should be added to allow compiling and running the C source implementation using project make commands (as documented below).
9. The README should be updated to include documentation for the added C API.

To provide a concrete example of what a PR adding the desired method should contain, see #3354, which is a PR adding a C implementation for the CDF of an arcsine distribution. This should provide an idea of what is expected.

Prerequisites
Review JavaScript implementation in lib/main.js and its required modules to identify all stdlib functions used.
Verify C implementations exist for each required function.
