This takes gopherjs node-syscall version at https://github.com/gopherjs/gopherjs/tree/master/node-syscall into a separate project with a package.json and provides downloadable binary assets.
The use case for this was for creating a VSCode extension that relied on Gopherjs and making system calls, that didn't rely on the end user (the VSCode user) to compile and copy syscall.node
to their extension's node_module
directory.
