Consider making fmtBodyString function public

[jackcipher]

Hi,
I've been working with go-resty and found the fmtBodyString function in the Request struct to be particularly useful. However, I noticed that it's currently a private function. I believe making this function public could benefit other users of the library.

Current Situation:

The fmtBodyString function is currently private and not accessible to users of the library.

Proposal:

Consider making the fmtBodyString function public, allowing users to access it directly.

Benefits:

1. Enhanced debugging capabilities: Users could leverage this function to inspect and format request bodies, which is particularly useful for debugging and logging purposes.
2. Custom implementations: Users could build upon this function for custom formatting or processing of request bodies.
3. Consistency: It would allow users to format body strings in the same way go-resty does internally, ensuring consistency across the application.

@Arpit529Srivastava Thanks for showing your interest. However, this request is not straightforward. Still, I have yet to decide to expose it. It does bring dependency on maintaining the API contract if it is exposed. I need to think about it.

You could look at other open issues and let me know which one you can tackle.
