add catch2 package (#74)

HW accel codecs bypass the CPU entirely — SIMD-optimized software
paths are irrelevant. Dropping x86asm removes ffmpeg's build-time
nasm dependency. nasm stays in setup.sh for x264 and libjpeg.

 * start a new top-level directory as a new package
 * `./test.sh` tests the building of all packages
 *  on pushes to `master`, wheels are built for our target platforms and pushed to a GitHub release
-*  the `releases` branch contains shim packages that allow pointing to a git branch and always getting the appropriate wheel for your platform
+*  each `release-<package>` branch contains a single shim package, so old lockfiles keep resolving even as new packages are added
