YAML Command and Tags

The client interprets specific commands and custom tags within the YAML file to configure and fetch data:

• `!dpGet`: Fetches data from a specified datapoint.
• `!dpConnect`: Establishes a connection to a datapoint and listens for changes.
• `!dpQuery`: Executes an SQL-like query to retrieve data.
• `!globalVariable`: References a global variable defined in the YAML file.
