feat: add update frequency and operation mode parameters to MQTT client

[AndyTempel]

This pull request adds support for configuring the MQTT client's update frequency and operation mode when creating a VRM MQTT client, providing more flexibility for users of the library. The changes also ensure that the update frequency is safely bounded between 0 and 300 seconds.

MQTT Client Configuration Enhancements

• Added update_frequency and operation_mode parameters to both the VRMMQTTClient constructor and the get_mqtt_client_for_installation method in client.py, allowing callers to specify how often updates are received and the operational mode of the MQTT client. [1] [2]
• Ensured the update_frequency value is clamped between 0 and 300 seconds for safety and reliability.
• Updated imports in client.py and mqtt.py to include the new OperationMode type from victron_mqtt, supporting the new parameter. [1] [2]
• Passed the new parameters (update_frequency_seconds and operation_mode) to the base VictronMQTTHub class in VRMMQTTClient, ensuring the configuration is applied at the hub level.

Pull request overview

This pull request adds support for configuring MQTT client update frequency and operation mode when creating a VRM MQTT client. The implementation adds new parameters to both the VRMMQTTClient class and the get_mqtt_client_for_installation method, with safety bounds for update frequency (0-300 seconds).

Changes:

• Added update_frequency and operation_mode parameters to VRMMQTTClient.__init__ with validation logic
• Updated get_mqtt_client_for_installation method signature to accept these parameters
• Imported OperationMode from victron_mqtt in both files
