Decouple logic from interactive grid component
Browse files Browse the repository at this point in the history 
Fixes nicolasperez19#16

Decouple logic from the interactive grid component.

* Add `src/utils/micLogic.ts` to export functions for handling microphone positions, zoom, pan, modes, mouse interactions, coordinate conversions, and numpy array string generation.
* Modify `src/components/MicMasterFlex.tsx` to import functions from `src/utils/micLogic.ts` and replace state management, event handlers, and numpy array string generation with utility functions.
* Add `src/utils/micLogic.test.ts` to test handling microphone positions, zoom, pan, modes, mouse interactions, coordinate conversions, and numpy array string generation.
