Enhance MakerPoints configuration and logic

- Added new configuration options for band-specific order amounts in `config.ts`.
- Implemented conditional logic in `MakerPointsEngine` to utilize the new band amounts based on the Binance depth cancel setting.
- Refactored order amount handling to improve clarity and maintainability.
