Support different error handling policies

As described here.

E.g. might make sense to implement:

• fail fast, i.e. throw instead if yielding exceptions
• fully defensive, i.e. ignore exceptions instead of yielding

That would require cooperation from either underlying data providers, or we could decorate them or something. Perhaps, makes more sense to do it on the HPI level.

Timezone resolution is perhaps one place where it would make a lot of sense -- in many case it's not super bad to fallback on UTC or use local timezone. But tricky to make it generic enough.
