feat(response): Return an integer representing the HTTP status code

[0x676e67]

This pull request includes several formatting changes to the rnet.pyi file and a functional addition to the src/response.rs file. The changes in rnet.pyi primarily involve the removal of blank lines and minor adjustments to class definitions, while the src/response.rs file introduces a new method to the Response class.

Formatting changes in rnet.pyi:

• Removed blank lines between class definitions and within class bodies to improve readability. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17]

Functional addition in src/response.rs:

• Added a new method status to the Response class to return the status code as an integer. This method is marked with the #[getter] and #[inline(always)] attributes to ensure efficient access.
