refactor: change bot messages and fix structure

[waream2]

I just went in and changed the file structure for cleaner imports. Using index as the the entry and exit point of all the modules in each directory. That way we can just import all of the modules needed from one place, as opposed to several imports.

Also the function that was checking if a channel had any points for !points wasnt working for me to i reworked it, please take a look and let me know if i missed something.

Last, I just updated the Bot's voice to be more playful.

i made some small fixes:

in the db.js:

• changed the place where the checkDB function is created and invoked.
• changed where the const db = new LowSync(new JSONFileSync("db.json")); is created.
• added const { points } = db.data; everywhere that is need to avoid breakages with points being Unknown.

in givePoint.js:

• added reaction in case it can't find id in the mention (see if you like the message).
• added an escape () necessary in a message.

in reportChannelPoints.js:

• change the text from "There's no points" to "There are no points"

in getUserIdFromMention.js:

• added optional chaining in case the result of the regex search returns null

beyond that I have no issues with your changes, and the messages are actually more fun now :)
