Add a bore-sight to know where the front of the robot is pointing

Fixes nicolasperez19#19

Add a bore-sight feature to indicate the front of the robot.

* **MicMasterFlex Component**:
  - Import `ArrowUp` from `lucide-react`.
  - Add a new state variable `orientation` to manage the robot's orientation.
  - Update `handleMouseMove` to handle bore-sight orientation.
  - Add a visual representation (arrow) to show the robot's front direction.
  - Update `generateGridLines` to include the bore-sight feature.
  - Update `getCursor` function to include a new mode for adjusting the bore-sight.
  - Add a button to the toolbar for adjusting the bore-sight.

* **README.md**:
  - Add a section to describe the new bore-sight feature.
  - Update the demo section to include the bore-sight feature.

 ## 📸 Demo

+The demo now includes a bore-sight feature to indicate the front of the robot. This feature helps in visualizing the robot's orientation and front direction.
+
 ## 💡 Project Motivation
 **MicMasterFlex** was born out of challenges encountered during the [*Robots as Furniture*](https://github.com/robotsasfurniture/passive-sound-localization) project at [Brown University Human-centered Robotics Initiative](https://hcri.brown.edu/), where configuring a microphone array for sound localization required precise positioning of multiple microphones.

+## 📝 Bore-Sight Feature
+
+The bore-sight feature in MicMasterFlex allows users to visualize the front direction of the robot. This is particularly useful for applications where the orientation of the robot is crucial. The bore-sight is represented by an arrow on the grid, indicating the direction the robot is facing.
+
+### How to Use
+
+1. **Adjust Bore-Sight Mode**: Select the "Adjust Bore-Sight" mode from the toolbar.
+2. **Drag to Adjust**: Click and drag on the grid to adjust the orientation of the bore-sight arrow.
+3. **Visual Feedback**: The arrow will update in real-time to show the new orientation.
