Update lr.js

[nerdkapilgupta]

Hi there i had made below changes for better and improve readability in this lr.js file.

Replaced the usage of var with Const and let for variable declarations, ensuring better variable scoping and immutability where applicable.

Added comments throughout the code to provide clarity on the purpose and functionality of each section.

Extracted the https and path modules into separate require statements for better code organization and easier maintenance.

Simplified the conditional statement for checking the presence of apiKey and apiSecret in the configuration. Instead of using the === undefined comparison, I used the config.apiKey === undefined and config.apiSecret === undefined conditions directly in the if statement.

Introduced a new constant HELPER_PATH to store the path of the helper module, using the path.join function.

Refactored the request function by extracting repeated code into separate variables to improve code readability. Specifically, I moved the code related to isApiSecret, headers, and queryString into separate sections with meaningful variable names.

Simplified the conditional statement for checking the presence of formData before writing it to the request.

Renamed the response variable inside the resp.on('end') callback to parsedResponse to better reflect its purpose.

Updated the error message in the resp.on('end') callback to be more descriptive, specifying that a server error occurred.

Grouped related APIs together under separate sections using object properties, such as accountApi, roleApi, sottApi, etc., to enhance code organization and improve readability.

Many of these changes are covered in my PR: #27

A main point of my changes was eliminating the reliance on any file system calls as they cause incompatibility with browser, as well as webpack or any post processing.
