* don't enter light sleep while the screen is on
* any time we wake from light sleep, briefly blink the led
* Use Neo-M8M API to put it in sleep mode
* turn light sleep on aggressively (while lora is on but BLE off)
* retest BLE software update for both board types
* default to enter deep sleep if no LORA received for two hours (indicates user has probably left the meshS)

* While in ON: If it has been more than screen_on_secs since a press, lower to DARK
* While in DARK: If time since last contact by our phone exceeds phone_timeout_secs (15 minutes), we transition down into NB mode
* While in DARK or NB: If nothing above is forcing us to stay in a higher mode (wait_bluetooth_secs, min_wake_secs) we will lower down to LS state
into either LS or SDS levels. If either phone_sds_timeout_secs (default 1 hr) or mesh_sds_timeout_secs (default 1 hr) are exceeded we will lower into SDS mode for sds_secs (default 1 hr) (or a button press). Otherwise we will lower into LS mode for ls_secs (default 1 hr) (or until an interrupt, button press)
* While in into LS: If either phone_sds_timeout_secs (default 1 hr) or mesh_sds_timeout_secs (default 1 hr) are exceeded we will lower into SDS mode for sds_secs (default 1 hr) (or a button press).
* Any time we enter LS mode: We stay in that mode for ls_secs (default 1 hr) (or until an interrupt, button press)
TODO: Eventually these scheduled intervals should be synchronized to the GPS clock, so that we can consider leaving the lora receiver off to save even more power.
TODO: In NB mode we should put cpu into light sleep any time we really aren't that busy (without declaring LS state) - i.e. we should leave GPS on etc...
