(obsidian): Add support for locations to tags #159
Description
As an Obsidian user, I want my Obsidian Task formatted tasks to include the location, so I don't lose my RTM data.
Background
The obsidian command reformats RTM tasks to the Obsidian Task format, but it doesn't handle locations.
Locations should be a nested tag location/{location name}
They are currently returned in the RTMTask as a location id
location_id: 258303
We're going to need to lookup the locations (hopefully the rtm-api already includes that) and then map them. And if not here is the documentation for it https://www.rememberthemilk.com/services/api/methods/rtm.locations.getList.rtm
