feat: Implement OLED display support and custom icons for 128x32 displays

- Added OLED functionality in keymap.c with custom rendering for layers and modifiers.
- Created a Python script to generate simple icons for OLED displays.
- Introduced a new rules.mk file to enable OLED features for the keymap.
- Developed an OLED font helper script for visualizing and designing custom graphics.
- Redesigned OLED layout to fit 128x32 displays, optimizing space for logos and layer indicators.
- Implemented flow tap functionality in flow_tap.c for enhanced key responsiveness.
