PARQUET-1091: Fix README links
Multiple links in the code base, including images and build status in README.md, are still pointing to the old `Parquet/parquet-format` GitHub repository, which is now removed. This PR tries to fix them.
Author: Cheng Lian <li...@gmail.com>
Closes #65 from liancheng/fix-readme-links and squashes the following commits:

Parquet is built to support very efficient compression and encoding schemes. Multiple projects have demonstrated the performance impact of applying the right compression and encoding scheme to the data. Parquet allows compression schemes to be specified on a per-column level, and is future-proofed to allow adding more encodings as they are invented and implemented.
