Fix three round-trip bugs found by the OGC conformance tests
- KML serialized a parsed NetworkLinkControl after the document's root
feature instead of before it, producing output that failed fastkml's own
bundled schema. xml_subelement_list_kwarg groups parsed children by class
in registration order rather than preserving document order, so reorder
KML's registration to put NetworkLinkControl first -- the XSD allows at
most one of each, so a fixed order is always schema-compliant regardless
of source order.
- Pair.style had no StyleMap variant, so a <Pair> containing a nested
<StyleMap> silently parsed as style=None. Add StyleMap to Pair's registered
classes and type annotation (as a forward reference, registered after
StyleMap is defined further down the same file).
- Enum-typed attribute values were parsed via a straight `enum_class(text)`
call, which rejected namespace-prefixed XSD QName values like
SimpleField's type="xsd:string" -- even though "string" is a valid
DataType value. Strip a leading prefix before the lookup in the one shared
helper (_get_enum_value) used by every registered enum attribute.
Updates the three tests that had pinned the old broken behavior as a
regression baseline to assert the now-correct behavior instead, with real
recomputed diff counts. Adds changelog entries for all three fixes.
