yargs-parser security update

[jamie-pate]

npm audit is now complaining about a security advisory in the 14.0.0 version of yargs-parser... seems like the fix is to upgrade to >= 15.0.1: https://github.com/advisories/GHSA-p9pc-299p-vxgp

BREAKING CHANGES rework collect-unknown-options into unknown-options-as-args, providing more comprehensive functionality

@jamie-pate can you provide full steps to reproduce this output?

My npm audit tells about some other moderate stuff.

From what I can tell typed-cli depends on 20+ version of yargs-parser: https://github.com/int0h/typed-cli/blob/master/package.json#L30

If you want you can try to upgrade the deps yourself and submit a PR. If it's going to be only deps update and it passes the tests I'll merge it.
