Documentation needs updating for Logic Analysis

[pickeditmate]

https://greatscottgadgets.github.io/greatfet-tutorials/logic-analysis.html shows gf.spi.transmit("GreatFET") bot doing this on Python3 errors out.

Instead I used gf.spi.transmit(b"\x88\x88\x88\x88")

Thank you. I will add a documentation update to my to do list.
