Description

• Motivation
  Since the regex should capture many scenarios, it ends up being super large and ugly. Even if its then compiled into an ugly large one, I would like to be able to define and, more importantly, name a few ones.

• Proposal
  Allow users to use this:

{spellcheck,
 [{ignore_regexes,
   #{eunit_files => "eunit",
      maps_in_comments => "=>",
      io_format_stuff => "~t",
      semver => "~>",
      …
    }]}.

instead of this:

{spellcheck,
 [{ignore_regex,
   "(eunit|=>|~t|_|~>|…"}]}.
