Update dependencies with vulnerabilities

Hi there!

Thanks for the nice npm package to use the Photoshop API, it really made my current automisation task easier.

When working with the package I realized that it uses some outdated npm dependencies. Especially the `swagger-client` has already some newer versions available that fix vulnerabilities. It should be safe to at least update its version from `3.9.6` to the current version `3.19.10`. This would already fix a lot of reported vulnerabilities. Here is a part of the report:

```
# npm audit report

cross-fetch <=2.2.5 || 3.0.0 - 3.1.4 || 3.2.0-alpha.0 - 3.2.0-alpha.2

```

Start with the npm dependency manifest and lockfile, then run npm audit to reproduce the reported vulnerabilities. Update the declared swagger-client dependency from 3.9.6 toward 3.19.10, check compatibility with the package, and confirm the audit results and existing tests.
