0.38: Don't rewrite settings file on every boot!
0.39: Move GB message handling into a library to reduce boot time from 40ms->13ms
0.40: Ensure we send health 'activity' message to gadgetbridge (added 2v26)

HRM data is stored as a number representing the best/average value from a 10 minute period.
## Usage in code
You can read a day's worth of health data using readDay, which will call the callback with each data packet:
```
require("health").readDay(new Date(), print)
// ... for each 10 min packet:
{ "steps": 40, "bpmMin": 92, "bpmMax": 95, "movement": 488,
"battery": 51, "isCharging": false, "temperature": 25.5, "altitude": 79,
"activity": "UNKNOWN",
"bpm": 93.5, "hr": 6, "min": 50 }
```
Other functions are available too, and they all take a `Date` as an argument:
```
// Read all records from the given month
require("health").readAllRecords(d, cb)
// Read the entire database. There is no guarantee that the months are read in order.
require("health").readFullDatabase(cb)
// Read all records per day, until the current time.
// There may be some records for the day of the timestamp previous to the timestamp
require("health").readAllRecordsSince(d, cb)
// Read daily summaries from the given month
require("health").readDailySummaries(d, cb)
// Read all records from the given day
require("health").readDay(d, cb)
```
## TODO
* `interface` page for desktop to allow data to be viewed and exported in common formats
