Reduce Mojang API calls

[Cryptizism]

User gave us some info and we can act accoridingly:

Mojang will keep imposing strict rate limits because me and a few other people are making millions of API requests per day to the Mojang API to make a full archive of more than 56 million UUIDs, player names, name change history, and skins for historical purposes. You should distinguish players between UUID versions rather than using the Mojang API and hitting rate limits.

There is no documentation since I created this project for myself which is used for laby.net Coverage as an example but I have made my code fully open-source for other people to take a look at: https://github.com/ItzLevvie/uuids/blob/4f0d6ca00c7a64e28c2b112e1c1bdedae49222a5/launch.js

More specifically, this code below:

[...]

// Minecraft puts all players under UUID version 4.
if (uuids[14] === "4") {
    Chat.log("§a" + players + " §fwith §a" + uuids);
    FS.open("validPlayers.txt").append(players + "\r\n");
    FS.open("validUUIDs.txt").append(uuids + "\r\n");
    FS.open("DEBUG.txt").append(players + " (player) with " + uuids + " (UUID version 4)" + "\r\n");
}

// Servers like Hypixel puts all NPCs under UUID version 2.
if (uuids[14] === "2") {
    //Chat.log("§4" + players + " §fwith §4" + uuids);
    FS.open("invalidPlayers.txt").append(players + "\r\n");
    FS.open("invalidUUIDs.txt").append(uuids + "\r\n");
    FS.open("DEBUG.txt").append(players + " (NPC) with " + uuids + " (UUID version 2)" + "\r\n");
}

// Servers like Hypixel puts all nicked players under UUID version 1.
if (uuids[14] === "1") {
    Chat.log("§4" + players + " §fwith §4" + uuids);
    FS.open("invalidPlayers.txt").append(players + "\r\n");
    FS.open("invalidUUIDs.txt").append(uuids + "\r\n");
    FS.open("DEBUG.txt").append(players + " (nicked player) with " + uuids + " (UUID version 1)" + "\r\n");
}

[...]
