Clock revamp

📢 Announcement

• Don't forget to get the new and updated Irrigation Unlimited companion card https://github.com/rgc99/irrigation-unlimited-card. A compact card where you can monitor and control your system (enabled/disable, manual run, adjustments).

⭐ New features

• Revamped clock. Now offers two modes fixed (legacy) and seer (default). The seer mode deprecates the granularity setting and fixes it at 1. This will increase accuracy and improve responsiveness without any additional CPU resources. CPU resources in idle state are almost nil.

• Update readme with new clock settings.
