Improve subscription disposal
feat(ReadFrom): rename Position to ReadFrom
This is a breaking change, but since Snicket is pre-1.0, I only want to
trigger a minor bump. Once I have shipped a production application
using Snicket, 1.0 will be released.
fix: don't detach subscription until disposed
This fixes an issue where, if a subscription is disposed,
it would not be attached to the Store anymore, and so disposing
the Store wouldn't wait for the subscription to finish.
