tmi.js 1.4.3 on Node.js NPM

Parse the badge-info tag like badges. This offers some information about certain badges in the badges tag.
- This means that the user has the 12-month subscriber badge but more specifically have subscribed for 21 months:
```
{ "badge-info": { subscriber: "21" }, badges: { subscriber: "12" } }
```
Automatically unescapes strings in the tags. This replaces "\\s", "\\:", "\\n", and "\\r" with " ", ";", "" (empty), and "" (empty) respectively.
```
"Channel\\sSubscription\\s(Schmoopiie)" // Input
"Channel Subscription (Schmoopiie)" // Output
```
Added the event "primepaidupgrade". Fires when a user converts from a Prime subscription to a regular subscription. Their subscription will continue after the Prime subscription ends.
```
client.on("primepaidupgrade", (channel, username, methods, userstate) => {});
```
Removed extra-utils from the library. This wasn't documented nor recommended and would be better supplied by userland anyway.
Fixed a case when joining a channel that no longer exists would cause the .join() command's callbacks to register incorrectly. (#342)
