feat: an option to throw error of result

[anatawa12]

Closes #119

[oscartbeaumont]

Looks great but I recon we replace throw_error_of_result: boolean with something like error_handling and the following enum:

/// The mode which the error handling is done in the bindings.
pub enum ErrorHandlingMode {
   /// Errors will be thrown
   Throw,
   /// Errors will be returned as a Result enum
   Result,
}

so in the future when we solve #89 we can just add a variant for it.

Also feel free to ignore CI, happy to merge with it failing cause that's all problems on main.

I have reimplemented with ErrorHandlingMode enum
