Flatline detection

[luccalb]

User Story

1. As a RTDIP user
2. I want to detect flatlining sensor input
3. So that react accordingly and e.g. check the sensor for errors

Additional context

• we already have a component for missing data, which could be extended [Component] Identify missing data #2

Acceptance Criteria

• A component exists that
  • receives a list of columns to watch for flatlining (a series of null or 0 values)
  • receives a tolerance timespan, if the flatlining period is longer than this, it should output a warning
  • it shouldn't manipulate the data itself

Definition of Done

• Test cases have been created and are running successfully
• Documentation for the new component was added
• Github Actions are running without errors
