rxjs-throw-error option to specifiy error names

See original GitHub issue

I have in an Angular project warnings for rxjs-throw-error on code like this.

throwError(new HttpErrorResponse({}))

I have worked with subclassing Error on other projects before as well.

Would you consider a PR adding an option to set error names.

eg.

"rxjs-throw-error": {
  "options": { "errorNames": ["Error", "HttpErrorResponse"] },
  "severity": "warn",
}

@NickLydon It’s possible that this issue will be resolved with the changes in 4.29.2 - as that release includes an update to tsutils-etc that looks at implements clauses.

Good to know.

For what it’s worth, me throwing HttpErrorResponse is only in tests since Angular throws them otherwise. So I can easily disable them.
