wordlist.rb

• Switched to using require_relative to improve load-times.

• Added support for reading zip (.zip) and 7zip (.7z) compressed wordlist
  files.
• Added support for building zip or 7zip compressed wordlist files.

CLI

• -f,--format now accepts zip and 7zip format values.

• Fix reading of compressed wordlists on macOS.
  • macOS's version of zcat, bzcat, and xzcat do not accept a file path
    argument, but instead require the compressed input be piped or redirected
    into them (ex: zcat < path/to/file.gz).

CLI

• Fixed a bug where operator options (ex: --power 3) were not being applied
  to the wordlist. (issue #22)

• Require Ruby >= 2.0.0.
• Added frozen_string_literal: true magic comments.
• Flush the output after each line is written in Wordlist::Builder.
  This allows for watching the wordlist file grow using tail -f.
• Fixed a bug in Wordlist::Lexer#parse where Unicode whitespace or other
  Unicode characters caused an infinite loop.
• Various documentation fixes.
