[python-win32] speed up win32com.client

[DANIEL POSE]

Sorry!!! my mistake!!! really there are a speed up, the timing using
late-binding is:
M_dimension= 512
R_dimension= 262144
t_block1= 3.00059867944
t_block2= 12.2370913063
t_block3= 0.488927223991
t_total= 15.7266172097

Then it is about half time using early-binding for my example. It is
wonderfull!!
