v0.10.1

Fixes

• Fix #70 - Ignore ANSI escape codes in parser. This allows the neodoc to
  be colored. For example:

  neodoc.run(`
  ${chalk.blue('Usage:')}
      prog <command> [<args>...]
  `);
  

  Thanks @matthewmueller for reporting

• Fix #71 - Do not trim help text. This allows the developer to keep some left
  padding on the help text. The leading and trailing newlines are still removed,
  however, in order to make working with JS template strings easy.

• Fix optional positionals in lax-placement mode.
  For example:
  usage: prog [foo] -a
  Would fail: -a foo before this patch because [foo] simply fails at -a
  and gets omitted. The added tests cover these cases.

• Fix 'stop-at' not working in groups in certain cases
