Filter notes by tags (#6)

Filter notes by their tags using `--tag "history, europe"`. To match notes associated with either tags, use a pipe `|` or `OR` (all caps), e.g. `--tag "inbox OR todo"`.

 ### Added
 
 * Support for tags.
-    * Many tag flavors are supported: `#hashtags`, `:colon:separated:tags:` and even Bear's [`#multi-word tags#`](https://blog.bear.app/2017/11/bear-tips-how-to-create-multi-word-tags/). If you prefer to use a YAML frontmatter, list your tags with the keys `tags` or `keywords`.
