Make SPI class and SDN pin optional #4

(Repeat of PR #3 ) Some platforms (e.g. ESP32) have multiple SPI buses; therefore, it would be nice if the user can choose which SPI bus to use. Also, I've made the SDN pin optional since there are also cases when the user may want to use external circuitry to perform automatic POR for the Si4432.

Thanks for the PR.

Sorry for the misunderstanding.
