A rewrite of the argument parsing portions of the `rad issue` subcommand
using `clap` instead of `lexopt`.
From a user's perspective, the look-and-feel of `rad issue` does not
change much. Although, the most prominent change is to rely on
`clap`'a default error template which looks a bit different from what we
use usually (`error: ...` vs. `✗ Error: ...`).
Leaving the above restriction aside, subcommand mis-usage is
reported more verbosely.
Also configure `clap` to use colored output for errors and help pages.
In help output, headers are colored with `Magenta` to match the overall
CLI styling.
Specify a type that captures the different actions that can be take
when using the `comment` command: `Comment`, `Reply`, and `Edit`.
Move the functions that run the corresponding actions into a `comment`
module.
To preserve the "default command" behaviour being `rad issue list`,
e.g., `rad issue --solved` behaving like `rad issue list --solved`,
introduce a new type `EmptyArgs`to also parse arguments without a
subcommand. In case no subcommand was parsed, construct `Command::List`
with from `EmptyArgs`.
