Doesn't work with ACSM files from Google Play Books

[tclimis]

Bug description

This is probably more of a feature request than a bug, but it appears that the acsm files from Google Play Books are a different format, which causes the following error when trying to open them:

Traceback (most recent call last):
  File "/usr/lib64/calibre/calibre/customize/ui.py", line 175, in _run_filetype_plugins
    nfp = plugin.run(nfp) or nfp
  File "calibre_plugins.deacsm.__init__", line 324, in run
    success, replyData = fulfill(path_to_ebook, deacsmprefs["notify_fulfillment"])
  File "calibre_plugins.deacsm.libadobeFulfill", line 322, in fulfill
    mimetype = acsmxml.find("./%s/%s/%s" % (adNS("resourceItemInfo"), adNS("metadata"), dcNS("format"))).text
AttributeError: 'NoneType' object has no attribute 'text'

The issue is that these ascm files do not have the <metadata> tag at all. <resourceItemInfo> instead looks like this:

<resourceItemInfo>
        <resource>urn:uuid:bc30db2e-38bf-5956-2221-bdf7e1e7e0f5</resource>
        <resourceItem>1</resourceItem>

Any non-working ACSM file is a bug, as this plugin is supposed to work with all of them. Thanks for the report, the bugfix f9fbc4172a5d44f95ffd50b0f105f351b91ea8d7 will be included in the next release.
