## Description This pull request adds a file parser for cheat code support. If a file named the same as the selected rom with the extension .cht is found, it will attempt to parse the file for cheat codes and place them in `menu->boot_params->cheat_list` per the cheat backend API. Cheat files should be formatted this way: ``` # Super mario 64 infinite lives 8033B21D 0064 # 120 stars 80207723 0001 8020770B 00C7 50001101 0000 8020770C 00FF ``` The parser ignores lines that start with a '#', are under 12 characters or over 15 characters. Every other line should be valid cheat code inputs with the code on the left, and the value on the right separated by a space. ## Motivation and Context <!--- What does this sample do? What problem does it solve? --> Adds some initial cheat support in the frontend to allow users to modify their games more easily, and take advantage of the backend API. ## How Has This Been Tested? Tested on real hardware with a Summercart64 and Super Mario 64. ## Screenshots <!-- (if appropriate): --> ## Types of changes <!--- What types of changes does your code introduce?
