Refactor parseShapes function to simplify property checks and improve…

… readability

- Combined checks for properties.P and properties.L into a single conditional statement.
- Replaced separate blocks for properties.P and properties.L with a ternary operator to set the type (0x01 for P, 0x02 for L).
- Updated the loop to start from 0 instead of 1 for consistency and clarity.
- Preserved the logic for reading buffer values and updating the buffer position after each iteration.

These changes streamline the function without altering its core behavior.
