[FEAT]: Allow request customization

[VanishMax]

Description

Hi! I loved reading and using this library, it is simple yet powerful.

There was an issue for me while making requests. It is common to provide additional headers like mode or authorization, or even change methods for some cases. Therefore, I'd want to propose extending the request logic by adding the requestOptions: RequestInit property and pass it to fetch like this: const response = await fetch(this.props.url, this.props.requestOptions);

Thanks for your issue and the like!
I apologize that I didn't take fetch's configurability into account during the initial design, I'll be adding that feature as soon as I can this week!

@codeacme17 I could implement it in the next hour if you're alright with that.
