Add support for SPI devices that use separate GPIO outputs for Data/Command and Reset

[AdamJSchofield]

And I'll add a full disclosure that I am fairly inexperienced with IoT things in general but I have spent several days in the weeds on this so I'm fairly comfortable with the basics of SPI. But for example, I just learned the difference between hardware/software SPI. I suspect that my device doesn't use hardware SPI and using software SPI may resolve some of the issues with my demo project.

Hey @AdamJSchofield, thank you so much for your contribution 😃. I noticed you already sent out a PR, we'll take a look soon to be able to get it in.

@joperezr Thanks for taking a look! As I mentioned on the draft PR, I've worked out some issues and am just polishing up my branch for review. I will probably close this issue now that I've got things figured out and keep discussion on the PR. Unless you prefer an issue for every PR.

[AdamJSchofield]

Closing because I've worked through most of the issues I was having. Will mark the PR as ready for review in the next few days.
