Node 16.x deprecations and problems.

[kaladay]

I've recently upgraded my node to a 16.x version and I now get this warning.

(node:5029) [DEP0147] DeprecationWarning: In future versions of Node.js, fs.rmdir(path, { recursive: true }) will be removed. Use fs.rm(path, { recursive: true }) instead

Check if fs.rm(path, { recursive: true }) can be used on older versions of node as well to ensure compatibility.
If it is possible to make this change without breaking not too old releases (node 14.x and node 12.x), then it may be worth making this change.

(node:7704) [DEP0148] DeprecationWarning: Use of deprecated folder mapping "./" in the "exports" field module resolution of the package at weaver-components/node_modules/tslib/package.json.
Update this package.json to use a subpath pattern like "./*".

Installing to local npm (Verdaccio) errors with:

npm ERR! code ENEEDAUTH
npm ERR! need auth This command requires you to be logged in.
npm ERR! need auth You need to authorize this machine using `npm adduser`

This might be resolved with this PR:

• Build components with Node 16 or greater. tamu-library-components#430

I think this should be reviewed to see if it is solved or not, so I am moving this into needs review.

Still happens, despite the changes in the above referenced PR.
