Feature request: add support for querying Activity Summary objects from HealthKit

[michaelyoon]

ActivitySummaryTypeIdentifier is included in the definition of ObjectTypeIdentifier:

export type ObjectTypeIdentifier = CharacteristicTypeIdentifier | SampleTypeIdentifier | typeof ActivitySummaryTypeIdentifier;

But there does not appear to be a way to execute a HKActivitySummaryQuery in the API?

I may be missing something, but, if not, please consider adding a queryActivitySummary() function, so that we can access Activity Ring data (Move, Exercise, and Stand goals).

Thanks for this great package!

Great idea, PRs are welcome! 🙂

I haven't worked with Swift before, but I imagine it's pretty straightforward, and the HealthKit docs on activity summary queries look reasonably clear.

I'll see if I can find the time to work on a PR.
