Binary Manifest

If you'd like to run your own custom binaries in a task, the bin-json-runner's got your back.

First, you'll need to create a manifest. This tells Computes where to find your binary archive for each platform. (IPFS-only at the moment). The following example is a simple binary that echos the input.
