refactor: replace OpenStruct with Data for performance and readability improvement

[Yash-Singh-Pathania]

Description

This PR refactors the codebase by replacing OpenStruct with Ordered Options for improved performance and immutability. The change ensures that Data is used to represent immutable objects, which provides better memory usage and execution speed compared to OpenStruct. No additional dependencies are required for this change.

@Paul-Bob would you be reviewing this ?

It feels unnatural to create a new class and override the initializer; it seems like we're not using the right tool for the job.

I came across this article discussing alternatives to OpenStruct:
https://dev.to/lorankloeze/alternative-for-rubys-openstruct-i72

I think we should consider using a more appropriate tool, such as Struct or Data.

Struct is significantly faster than OpenStruct (~80 times faster), although I’m unsure how it compares to Data. Let’s either research or run a quick benchmark, similar to the one in the article, to determine which option Struct or Data is faster, and proceed with that.

@Paul-Bob let me go through this quickly and run a quick benchmark for the same.

Thank you for working on this @Yash-Singh-Pathania

I've completed the PR by using Struct instead of previous approaches.
