This was based on the old PyBoard I2C methods. Now it is using
the recent methods for I2C.
Also: Fix init setting for 64x32 displays.
Note: This PR may not be overly important, but a few people stumbled over this non-working
driver, including me yesterday. I stumbled over the wrong 64x32 size setting.
Note2: It might be useful to implement the writevto() method for I2C, avoiding memory allocations for chained write.
