Add ShellOption, DeletedWrapper

Abstracts away option writing such that users no longer have to
understand scopt semantics. This adds a ShellOption class and a
HasShellOptions trait for something which provides one or more
ShellOptions. This refactors the FIRRTL codebase to use this style of
option specification.

Adds and uses DeletedWrapper to automatically generate
DeletedAnnotations.
