allow per-pipe ARC/ARD, refactor a few more double-negative options, fix ackTo pipe 0 test
bit more states setup tweaking
allow opts-less pipe opening
support numeric addresses (requires bit set in high nibble!)
add note about apparent silliness of requiring separate tx/rx mode
start working test towards pingpair-like functionality
avoid opening pipe while mode is pending
value-setting methods take a callback, which is weird with chaining syntax, but…
fix reset to work w/defaults
add verbose logging
get rid of test debug noise
don't log callback in execCommand
replace custom work queue with async-queue, see if it fixes issue where states are not finished setting when payload write/pulse happens
add note about another potential setStates optimization
