Fast(ish) special purpose bitbang spi over i2c 
with the i2c bus operating at 400kHz this achieves a 4.8kHz SPI clock
rate which could be worse.

It accepts the same style of init sequence as displayio.

tested by scoping the pins on the espressif lcd dev kit with a dummy init sequence:
```python
dotclockframebuffer.ioexpander_send_init_sequence(
    bus=bus,
    i2c_address=expander_addr,
    gpio_address=1,
    gpio_data_len=1,
    gpio_data=0xff,
    cs_bit=1,
    mosi_bit=3,
    clk_bit=2,
    init_sequence=init_sequence)
```
