[Satont]

Currently there are too many mutations occure, and code a bit (NOPE, A LOT) not clear.

Possible problem files:

• https://github.com/Satont/yakui/blob/master/src/bot/libs/cache.ts
• https://github.com/Satont/yakui/blob/master/src/bot/libs/parser.ts
• https://github.com/Satont/yakui/blob/master/src/bot/decorators/command.ts
