Early PandJS build with experimental fs support

PandJS early build with experimental support for file system operations.

Earliest public PandJS Linux build ever

First public PandJS build ever - Linux only

Early version, not perfect but usable. Everything under single executable.

Alpine Linux and missing glibc

PandJS is built and linked against glibc so if you want to use systems like Alpine Linux, you have two options:

1. build on your own against musl (it wil take 40 minutes + build infrastructure is still not perfect, not well tested under many configurations)

2. install libc6-compat using:

apk add libc6-compat
