expand and build_assimilator does not work

[qq309381]

• pixel_map.py, i delete two sentences

  assert self.bits_per_pixel % 8 == 0, "Unsupported pixel density"
  assert self.width * self.height * self.bits_per_pixel / 8 == len(self._proto.data)

• class sentdebot, i delete distribute_works()

or it won't work!

problem : train probe -- good build pylons -- good expand -- bad build assimilator -- bad

even it get so much money ,it does not work

win10 64 bits python 3.6.8

i have changed the sc2 from stable to develop version , pixel_maps and distribute_work both ok now, but expand and build assimilator still do not work. build stargate and train spider work correctly i upgrade the python from 3.6.8 to 3.7.3 now
