We are actually using a SHT2x in one of our projects, which does use I2C, and I just assumed the STH1x were the same. You are write, you will have to write a custom component to access it, or as dave says use bit banged i/o, with PIOs for example. If you really need the humidity you can try the SHT20 instead, that uses a I2C bus. If you only need temperature there are lots of other I2C sensors, such as the FM75.
