Chore/Replace uglify with terser

[iusztin]

I tried to deal upgrade serialize-javascript: GHSA-hxcc-f52p-wc94 and kind-of: GHSA-6c8f-qphg-qjgp
Unfortunately, those depend on rollup-plugin-uglify, which is almost not maintained: TrySound/rollup-plugin-uglify#87
The author recommends using rollup-plugin-terser instead: TrySound/rollup-plugin-uglify#69

-> I replaced rollup-plugin-uglify with rollup-plugin-terser in this PR.

Unfortunately kind-of is still blocked because of chokidar-cli: https://github.com/kimmobrunfeldt/chokidar-cli - but this package is not maintained well, and also only used for local development -> I decided not to pursue the kind-of upgrade further.

Please review.

I think it's not blocked because we can just avoid only the affected versions: >= 6.0.0, < 6.0.3
Can you try to remove the entry of kind-of@^6.0.0, kind-of@^6.0.2 in yarn.lock and execute yarn install? In our yarn.lock, only that entry is affected.

Ah, there is a lower bound! I overlooked that!
I pushed changes. Please take a look again.

LGTM! Thank you for dealing with this security fix :)
