Add transformTagName to the XMLBuilder

[pkuczynski]

XMLParser has option transformTagName, which allows to mutate tag names on parsing. Similar option would be very useful for XMLBuilder too.

Example usecase:

const builder = new XMLBuilder({
  arrayNodeName: 'book',
  transformTagName: (tag) => tag.toUpperCase()
})

const xml = builder.build([{ author: 'Joe Doe', title: 'Great book'}]);

would produce:

<book>
  <AUTHOR>Joe Doe</AUTHOR>
  <TITLE>Great book</TITLE>
</book>
