tei2imxml: Inline graphics check disallows height attribute for EOAinline

[kthoden]

Currently around line 1108:
If a graphic is rendered as EOAinline or EOAfigurenonumber (as a workaround for figures in footnotes), is decided by the number of attributes:

        if len(graphic_attributes) == 1:
            graphic.tag = "EOAinline"
            graphic.text = graphic_attributes["url"]
        elif len(graphic_attributes) == 2:
            graphic_parent = graphic.getparent()

Should be handled differently
