#1213 - Support geom_ref in list_subscriptions

Closes #1213

Sorry for the two fixes in one MR, but I'm also using this branch as a local build of the SDK while I wait for these fixes to be accepted and released.

Edit: Scaling this back to just 1213, turns out update_feature can't touch geometry, and therefore isn't useful to me.

Proposed Changes:

For inclusion in changelog (if applicable):

1. geom_ref now supported by list_subscriptions

Not sure I understand the typing failure here, if anyone's got some insight it would be appreciated

[tbarsballe]

Okay, I did a rerun of the typing check on main (which passed on the latest commit, when it was run about a month ago), and it failed this time around, with no code changes since the passed test.
Seems like somewhere in the dependency tree of our type checker, something's been released that now causes these failures, entirely unrelated to the changes in this MR.
