feat: Add Rice Distribution Base Package

[CodeMaverick2]

Issue

• [Link to issue RFC: add the Rice distribution #178]

Description

This pull request implements the base package for the Rice distribution in the @stdlib/stats/base/dists/rice namespace. The base package includes the essential functions such as the probability density function (PDF) and cumulative distribution function (CDF) for the Rice distribution. This serves as the foundational implementation, and additional functions will be added in subsequent PRs as per the guidelines.

@kgryte I've created a base package for rice distribution, If there are any issue do inform me and if we want to update the package to be more broad i can work on that if you say so

Thank you for working on this pull request. However, we cannot accept your contribution as this pull request does not follow project conventions.

We place a high value on consistency throughout the stdlib codebase, and this pull request was found to significantly deviate from stdlib conventions. We encourage you to closely examine other packages in stdlib and attempt to emulate the practices and conventions found therein.

• If you are attempting to contribute a new package, sometimes the best approach is to simply copy the contents of an existing package and then modify the minimum amount necessary to implement the feature (e.g., changing descriptions, parameter names, and implementation).
• If you are contributing tests, find a package implementing a similar feature and emulate the tests of that package.
• If you are updating documentation, examine several similar packages and emulate the content, style, and prose of those packages.

In short, the more effort you put in to ensure that your contribution looks and feels like stdlib—including variables names, bracket spacing, line breaks, etc—the more likely that your contribution will be reviewed and ultimately accepted. We encourage you to closely study the codebase before continuing to work on this pull request.

Thank you again for your interest in stdlib, and we look forward to reviewing your future contriubtions.
