* add support for SN74HC595 shift register * fix linter errors * more linter reported issues fixed * hopefully last linter error cleanup * one more linter fix * looks like the linter is always keeping stuff for later, is this the final fix? * add test Co-authored-by: Guillermo Ruffino <glm.net@gmail.com>
