`pnpm` packaging not working

While working on #267, I could not get pnpm functionality to work.

1. pnpm stores it’s deps in a subdirectory node_modules/.pnpm/ or some npm_reg folder for older versions with {package}@{version} folders so the rest of the packaging logic doesn’t pull it into external.
2. It fails at the install command saying the lockfile is out of date.
3. The list deps command is very broken because the list command without a depth only shows its top level dependencies.

At this point the pnpm functionality does not work. Not sure if there was a version which this is actually compatible with @floydspace? If you are after this functionality please leave a comment below and I’ll try and find some time to work on it.

I had a first take last week and discovered the incompatibility with lambda and the symlinked structure. I would absolutely love to fix this. But ultimately this is just a volunteer thing for me and sometimes it’s quite hard to pick up the tools after work

Hey @samchungy, it was contributed by @lulzneko, to be honest, I haven’t tested it and have never used it, maybe initially it worked. Please go ahead to fix it if possible.
