File limit of 99 on SD cards

Sometimes the midge stops recording in the middle, although not frequently.

	while (true)
	{
	if (audio_switch_get_position()==HIGH) sprintf(filename, "%dMicHi%d", drv_audio_get_mode(), fileCount);
	if (audio_switch_get_position()==LOW) sprintf(filename, "%dMicLo%d", drv_audio_get_mode(), fileCount);
	ff_result = f_stat(filename, &fno); // Check if the file already exists
	if (ff_result == FR_NO_FILE)
	{
	break; // File does not exist, break the loop
	}

	fileCount++;

I think there is an issue when the number of files reaches 99. As sometimes the file are split into multiple chunks this can be easily reached, and then it would not start recording microphone. Typically this happens way before the storage of 4GB/8GB is reached. I think it can be increased to 999, or removed.

The solution here is not to increase the file limit number but to figure out why the audio is getting chunked into several files and stop that from happening.

Just in case, in the current impl, this is limited to 99 due to the file system using 8.3 naming https://en.wikipedia.org/wiki/8.3_filename
