* Introduce shell module for basic serial shell with argument parsing * Introduce shell_cmd_list module for basic compile-time command registration * Harden USB handling to hang less and drop fewer inputs - Service tud_task() with periodic TC0 timer interrupt - Service cdc_task() with periodic TC1 timer interrupt - Handle shell servicing in main app loop - Add a circular buffering layer for reads/writes * Change newline prints to also send carriage return * Refactor filesystem commands for shell subsystem * Introduce new shell commands: - 'help' command - 'flash' command to reset into bootloader - 'stress' command to stress CDC writes Testing: * Shell validated on Sensor Watch Blue w/ Linux host * Shell validated in emscripten emulator * Tuned by spamming inputs during `stress` cmd until stack didn't crash
