A TIS-100 simulator and save validator

This is a validator for saves for the game TIS-100, designed to be used for the community-run leaderboard. Unlike other simulators, TIS-100-CXX includes definitions for the base game's levels and can generate suitable random tests for them.

Ensure you have a C++23 compliant compiler (clang 16+, gcc 14+).

1. clone repository
2. update kblib submodule: git submodule update --init --recursive
3. run cmake -B "path/to/some/build/dir" -S .
4. run cmake --build "path/to/some/build/dir"

The command-line API documented here is currently extremely basic and ad-hoc, and will be replaced soon.

If run with no arguments, TIS-100-CXX will run a very basic self-test. With the single argument generate, TIS-100-CXX will write layout and randomized input files compatible with Phlarx' tis simulator for all of TIS-100's main and second campaign's levels.

Otherwise, the first argument identifies a level by either name or id (for example, 00150 or "SELF-TEST DIAGNOSTIC" both refer to the first level of the main campaign) followed by a path to a TIS-100 source file, followed optionally by the word random, which will cause TIS-100-CXX to use a randomly generated test case.
Otherwise, it will use a hardcoded test case copied from the game. In any case, it will print whether the validation was successful or not, followed by either the score, or the reason it was not validated and how many cycles it took to fail.
