// 1. Starts parsing an array of message arguments containing "Top finishers: (nick1: 1000) (nick2: 2000)", where
// the "($nick: $value)" pairs can contain arbitrary nicknames + integer values and can repeat one to any amount of times
// 2. Join the array on spaces to a string, but skip the first two elements to remove "Top" and "finishers:"
// 3. Replace ") (" in the string with ";" - the semicolon is chosen as a temporary delimiter because it does not conflict with any other characters in the message
// 4. Replace ": " in the string with ":"
// 5. Replace "(" in the string with "" (relevant for the first nick/value pair)
// 6. Replace ")" in the string with "" (relevant for the last nick/value pair)
// 7. Now, we have a string like "nick1:1000;nick2:2000" - split it back into an array on ";"
// 8. The result is an array like "[nick1:1000, nick2:2000]"
