Add target zone estimation functionality and step time tests

[Nissa9902]

fixes issue #33

What Was Changed:

• Implemented real-time streaming of step times and target zones from the backend.
• Added functionality to estimate target zones based on step times received from the backend.
• Updated unit tests to verify the correct behavior of step time calculation and target zone estimation.
• Implemented a WebSocket connection to receive real-time step time and target zone data from the backend.
• Updated useStepTime to manage the state of step times and target zones, allowing dynamic updates to the UI.

Why It Was Changed:
This change was essential for providing real-time feedback to users during step time calculations, enabling them to visualize target zones and step times dynamically.

How It Was Changed:

• Created the target_zone_estimation.py module to handle the target zone estimation logic.
• Updated existing tests in test_step_time.py to verify the accuracy of step time and target zone estimations.
• Integrated Target Zone Logic with Frontend.
• Improved the WebSocket connection logic to ensure reliable streaming of step times and target zones from the backend to the frontend.

Some minor changes, but overall looks good for the code you have. Just need to implement the frontend connection.

Everything I asked for looks good!

Good job Nissa, I made a few changes to fix linter errors, batch process forcedata and invoke the streaming function from main.
