updated to use any version of pillow >= 2.9.0

This change allows installation of the module using Thonny (using pip install cImage). Without this, Thonny fails on both Mac and Windows to install the legacy 2.9.0 version of Pillow, which causes the cImage installation to also fail. Tested on Mac and Win.
