[Chore] Remove/refactor .clone() from the /ol/types folder where needed

[0xzoz]

Bounty - 2000 GAS

What is the issue

During the development of the initial implementation of 0L. Work was done quick to meet deadlines and because of this .clone() was used in some instances to speed up development. These need to be cleaned up.

What needs to be done?

• Go through the /ol/types folder in root and remove instances of .clone() by refactoring the code. This may include refactoring of related files that the code is coupled to.

Intention

This issue is part of the Tool Scrubbers Guild

The idea behind this issue is to create manageable first tasks for relatively novice prospective developers looking to learn more about Rust and 0L. Not all of the unwraps will need to be refactored and part of the exercise is determining if the .clone() could be refactored or if they are already best practice depending on the situation
