Change .find() to .some() wherever applicable

[TrojanerHD]

When I started writing this bot, I didn't know that Array.prototype.some() exists and used a workaround:

const found: T | undefined = array.find((elem: T): boolean => elem === something);
if (!found) console.log(false);
else console.log(true);

this can be changed to

const found: boolean = array.some((elem: T): boolean => elem === something);
console.log(found);

(In this case even to console.log(array.some((elem: T): boolean => elem === something));)
