Remove `log` table in detection module

[Peque]

Analyze the time it takes to perform the calculation and the size of the generated binary (it will probably be smaller).

If it is not too slow even without a FPU, remove the table and use math's log().

Log time with:

 void sys_tick_handler(void)
 {
+	float tcompute;
+
 	clock_tick();
+	stopwatch_start();
 	update_distance_readings();
+	tcompute = stopwatch_stop();
 	update_gyro_readings();
 	update_encoder_readings();
 	motor_control();
-	log_data();
+	LOG_DATA("[%f]", tcompute);
 }
