Support :annotations hint for timew command

I use tags to classify intervals and annotations to describe my activities for each interval. I want to check if a timer is running as I work, monitor the duration, and confirm that the tags and annotation are appropriate. The `timew` command is great for this. It's fast, easy, only shows the current interval, and provides and easy-to-read vertical output.

Checking the annotation requires `timew summary` plus any options wanted to filter the output. This works and is not difficult using `timew summary @1` (with annotations on by default).

Even so, showing the current annotation would be a nice addition to the `timew` output. This could be done with the `:annotations` hint, and ideally, configuration to show/hide annotations by default, just like the summary report.

I imagine something like this:

```
> timew
Tracking my-tag
Annotation My annotation describing what I am doing.
