Issue with table based encoders

In line 92 of ClickEncoder.cpp the value of the lookup table (+1 / 0 / -1) is stored in a uint8_t datatype, instead it should be stored in an int8_t type according to the possible values.

 

>  **uint8_t** tbl = pgm_read_byte(&table[last]); 
  if (tbl) {
	Serial.println(tbl);
    delta += tbl;
    moved = true;
  }
