        The optional parameter is not used, but rather included so we don't
        have to delete it from the parameter dictionary when passing as keyword
        args

        :param explicit:
            An int tag number for explicit tagging, or a 2-element tuple of
            class and tag.

        :param implicit:
            An int tag number for implicit tagging, or a 2-element tuple of
            class and tag.

        :param no_explicit:
            If explicit tagging info should be removed from this instance.
            Used internally to allow contructing the underlying value that
            has been wrapped in an explicit tag.

        :param tag_type:
            None for normal values, or one of "implicit", "explicit" for tagged
            values. Deprecated in favor of explicit and implicit params.

        :param class_:
            The class for the value - defaults to "universal" if tag_type is
            None, otherwise defaults to "context". Valid values include:
             - "universal"
             - "application"
             - "context"
             - "private"
            Deprecated in favor of explicit and implicit params.

        :param tag:
            The integer tag to override - usually this is used with tag_type or
            class_. Deprecated in favor of explicit and implicit params.

        :param optional:
            Dummy parameter that allows "optional" key in spec param dicts

        :param default:
            The default value to use if the value is currently None

            A byte string of the encoded contents of the value

    Builds an Asn1Value object generically, or using a spec with optional params

    :param class_:
        An integer representing the ASN.1 class

    :param method:
        An integer representing the ASN.1 method

    :param tag:
        An integer representing the ASN.1 tag

    :param header:
        A byte string of the ASN.1 header (class, method, tag, length)

    :param contents:
        A byte string of the ASN.1 value

    :param trailer:
        A byte string of any ASN.1 trailer (only used by indefinite length encodings)

    :param spec:
        A class derived from Asn1Value that defines what class_ and tag the
        value should have, and the semantics of the encoded value. The
        return value will be of this type. If omitted, the encoded value
        will be decoded using the standard universal tag based on the
        encoded tag number.

    :param spec_params:
        A dict of params to pass to the spec object

    :param nested_spec:
        For certain Asn1Value classes (such as OctetString and BitString), the
        contents can be further parsed and interpreted as another Asn1Value.
        This parameter controls the spec for that sub-parsing.

    :return:
        An object of the type spec, or if not specified, a child of Asn1Value

    Parses a byte string generically, or using a spec with optional params
