https breaks NlmXmlReader

[maddenfederico]

In the NlmXmlReader class

    def detect(self, fstring, fname=None):
        """"""
        if fname and not (fname.endswith('.xml') or fname.endswith('.nxml')):
            return False
        if b'xmlns="http://jats.nlm.nih.gov/ns/archiving' in fstring:
            return True
        if b'JATS-archivearticle1.dtd' in fstring:
            return True
        if b'-//NLM//DTD JATS' in fstring:
            return True
        return False

The NLM's JATS namespace URI uses https now, so my document wasn't being registered as compatible with NlmXmlReader
