    I am using Oleg's algorithm for reading an encoder using a lookup table, here:
    https://www.circuitsathome.com/mcu/reading-rotary-encoder-on-arduino

    But instead of this table of 16 bytes:

    static int8_t enc_states[] = { 0, -1, 1, 0, 1, 0, 0, -1, -1, 0, 0, 1, 0, 1, -1, 0 };

    I am using two tables of 8 bits each. The bits in these tables indicate sign bits and one bits
    of the generated results. This takes advantage of the fact that I can easily encode 3 values
