Added details to SMT parts
Low power delay rework

Avoid sleep/nap watchdog timer to improve accuracy, avoid sleep/wake
internet tent crashes - but at the cost of higher power usage.
Tweaks to cpu speed changes
Fix intermittent I2C write issue

Write to I2C one byte at a time to prevent intermittent case where two
bytes could be swapped.
Avoid case where button is held down

Only allow the button to be held down for 3 cycles to prevent case
where power may be drained if button is permanently held down.
Refactor code for LED pulse effect
Cleanup of comment spelling and blank lines
Define connection speed more clearly
Add new option for saving both raw and lux data

Adds a -both option and reworks code flow so that both a raw and lux
data file are created or appended to. This helps drastically speed up
logging if you need both for debugging.
