feat: can use escaped tokens inside quotes including quotes.
Change tokenizer to support:
cmd with arg "string with embedded \" double quote"
works for single quotes too. Mixed quotes can skip the \" or \'
escaping.
Also:
quoted cmds args "can include \n newline, \t tab and \r return"
Added a doc example, also tests for new feature.
