This squashed commit rolls up a series of changes designed to improve
Flodgatt's public API/module boundary. Specifically, this limits the
number of Items that are exported outside the top-level modules (in some
cases because they were already not needed outside that module due to
the earlier code reorganization and in some cases by using public
re-exports to export particular Items from a private module).
Similarly, this commit moves the `Event` struct to the `response`
module (maintaining privacy for the `Event`'s implementation details)
while re-exporting the `Id` struct that `Event` uses internally at the
top level.
All of these changes are made with the goal of making Flodgatt's code
easier to reason about in isolation, which should both make it easier to
maintain and make it easier for new contributors to make changes without
understanding the entire codebase. Additionally, having fewer public
modules will make documenting Flodgatt more extensively much easier.
When the `WHITELIST_MODE` environmental variable is set, Flodgatt
requires users to authenticate with a valid access token before
subscribing to any timelines (even those that are typically public).
