Fixes for migration to platform APIs v2

[daniel-k]

This PR fixes issues we overlooked when merging #47. It depends on #54 so that we can review the fixes in isolation and don't get distracted with code that has already been approved.

• remove Site.address: we don't publish this property anymore since v2
• refactor get_timeseries() to use POST with slightly changed schema in v2

Closes #45

Depends on

• Migrate to platform APIs #54

Merge #54 first, then retarget this PR to master and merge right after.
