Usemap for imgs

[asmanur]

Hello,

I have been trying to use interactive maps with tyxml, and have not been able to use the usemap attribute of the node to refer to the node, as illustrated in https://www.w3schools.com/tags/tag_map.asp

The a_usemap attrib constructor seems to exist but `Usemap is not allowed in img_attrib. It seems to me that it should be in there but maybe I am missing something?

It seems the usemap attribute is availble for object, but was forgotten for img! Could you add it ? You just need to patch Html_types.img_attrib.
