fix `typeinfo.LoadRegTypeLib` type annotation

[junkmd]

My priority has shifted to modifying other modules, so I hope someone else will finish this unfinished work.

Currently

comtypes/comtypes/typeinfo.py

Lines 511 to 516 in 30523b5

	def LoadRegTypeLib(guid, wMajorVerNum, wMinorVerNum, lcid=0):
	# type: (str, int, int, int) -> ITypeLib
	"Load a registered type library"
	tlib = POINTER(ITypeLib)()
	_oleaut32.LoadRegTypeLib(byref(GUID(guid)), wMajorVerNum, wMinorVerNum, lcid, byref(tlib))
	return tlib # type: ignore

Suggested change

def LoadRegTypeLib(guid, wMajorVerNum, wMinorVerNum, lcid=0):
    # type: (_UnionT[str, GUID], int, int, int) -> ITypeLib
    """Load a registered type library"""
    ...

Ratiole

The constructor arg of GUID will be casted to text_type.

comtypes/comtypes/GUID.py

Lines 40 to 42 in 30523b5

	def __init__(self, name=None):
	if name is not None:
	_CLSIDFromString(text_type(name), byref(self))

And str(GUID("xxxxxxxx-...")) will return 'xxxxxxxx-...'.

comtypes/comtypes/GUID.py

Lines 47 to 53 in 30523b5

	def __unicode__(self):
	p = c_wchar_p()
	_StringFromCLSID(byref(self), byref(p))
	result = p.value
	_CoTaskMemFree(p)
	return result
	__str__ = __unicode__

Thus, there is no problem guid argument is either str or GUID.

can you assign this to me?
