Title: Add Hough transform

Implemented the Hough Transform sample, adding the input image from the Rosetta website. Rather than use PNG and introduce another dependency, I converted it to PGM and wrote simple load/save support in Rust. Compares exactly with the output of the Go version (on which it was based).
