Mission: Build a Master of Orion (1993) Clone in Modern C++
Project Name: Orion Reborn
Create a faithful yet modernized spiritual successor / clone of the original Master of Orion (the 1993 classic that coined the 4X genre) using C++23, raylib for rendering/input/audio, and Dear ImGui (via rlImGui) for the user interface.
The game should capture the elegant, addictive gameplay loop of the original while leveraging modern language features, clean architecture, and cross-platform ease.

Often, when parsing, you encounter a point where you want to check if a string is one out of a set, as quickly as possible. E.g., if you are parsing URLs, the string must start with a protocol, and there is a finite list of protocols. There are many such problems. Think about YAML files where a parameter must take one out of 3 or 5 values.
If you have 5 strings (say http:, https:, file:, sftp:, ftp:), you may do 5 comparisons. This is obviously wasteful.

| This program serves as a comprehensive test suite for the consume_array and | |
| consume_object functions, which are designed to parse specific JSON structures | |
| using the simdjson library. The primary goal is to validate the parsing of | |
| arrays and objects that contain a string, a double, and an optional integer | |
| value. The test generates a large JSON array consisting of 200 elements: the | |
| first 100 are sub-arrays, and the next 100 are objects. This allows for thorough | |
| testing of both parsing paths under various conditions. | |
| The consume_array function takes a simdjson ondemand::array and extracts three |
