Angular v16 does not support view engine - please switch to ivy

[RobinKamps]

Since angular v16 does not support view engine anymore - please upgrade this lib to ivy.

          You can use `npm i --save @angular-ex/uploader` for Ivy engine. I hope my fork is useful while we wait for author upgrading to v13.
