* Add --value option to filter command
Modeled after fzf's --query option this allows the inital model to be
prefiltered.
Additionally, if the initial list, before being filtered by --value, is
empty then treat this as an error. Filtering an empty list doesn't make
sense.

This commit uses the embedded style struct for styling in all components. The most notable example is `gum write` where there are many styles that are used and composed for each component of the command.
