[Feature Request] Editing Permission with text files

**Is your feature request related to a problem? Please describe.**
Yes
Reason:
If you can edit the Permission with a text file
For example, I want to make the Pause function available to general users, but it is difficult to modify. So I want you to be able to edit it with an easy text file.

**Describe the solution you'd like**
I want you to be able to easily change the permissions of the command with something like .txt file or .ini file.

**Describe the basic flow/steps of using this feature**
How this feature would be used:
1. If there is permission.txt in the bot file
2. Please allow the user command DJ command to be modified freely.
3. If you move the Pause in the DJ command as a user command, you can use it as well.

**Have you confirmed that this idea is not already described here?**
Has confirmed.

**Finally**
Thanks for always patching hard !!

Start with issue #390 and review how existing permissions and DJ/user commands are represented, focusing on the Pause command example. Define the text-file format and how permission.txt would be discovered and applied; done means users can change command permissions without modifying code.
