Better History System

Better History System

Description

Rewriting the history system to not rely on strings so it will be easier to work with for other issues. Favors a struct instead of many string conversions until the moves actually have to be displayed.

This takes PR #64 a step further by getting rid of the option type and the string and replacing the tuple with a proper struct

How Has This Been Tested?

Please describe the tests that you ran to verify your changes. Provide instructions so we can reproduce. Please also list any relevant details for your test configuration

Ran through all cargo tests and played moves on the board to make sure the history still appeared correctly

Playing around some more, promotions aren't quite working right... I'll have to look into that

Fixed the promotions, going to wait to squash until the end because there might be more comments for stuff to change. Let me know what you think 😄
