pydocstyle: `addIgnore` and `addSelect` are not respected unless `convention` is set

Lines 48 to 59 in cc6d398

	if settings.get("convention"):
	args.append("--convention=" + settings["convention"])
	if settings.get("addSelect"):
	args.append("--add-select=" + ",".join(settings["addSelect"]))
	if settings.get("addIgnore"):
	args.append("--add-ignore=" + ",".join(settings["addIgnore"]))

	elif settings.get("ignore"):
	args.append("--ignore=" + ",".join(settings["ignore"]))

It is on or the other. But the docs say it is ok to use --add-ignore with say --ignore.

  Error Check Options:
    Only one of --select, --ignore or --convention can be specified. If
    none is specified, defaults to `--convention=pep257`. These three
    options select the "basic list" of error codes to check. If you wish
    to change that list (for example, if you selected a known convention
    but wish to ignore a specific error from it or add a new one) you can
    use `--add-[ignore/select]` in order to do so.

    --select=<codes>    choose the basic list of checked errors by specifying
                        which errors to check for (with a list of comma-
                        separated error codes or prefixes). for example:
                        --select=D101,D2
    --ignore=<codes>    choose the basic list of checked errors by specifying
                        which errors to ignore out of all of the available
                        error codes (with a list of comma-separated error
                        codes or prefixes). for example: --ignore=D101,D2
    --convention=<name>
                        choose the basic list of checked errors by specifying
                        an existing convention. Possible conventions: pep257,
                        numpy, google.
    --add-select=<codes>
                        add extra error codes to check to the basic list of
                        errors previously set by --select, --ignore or
                        --convention.
    --add-ignore=<codes>
                        ignore extra error codes by removing them from the
                        basic list previously set by --select, --ignore or
                        --convention.
