Added PHP and JS/TS submodules

[brainfoolong]

Hi there!

I've created 2 implementations of the ASCON cipher. One in PHP and one in TS/JS.

Hope you find this useful to add it to the submodule list.

Tests are done automatically in Github actions against different PHP versions and also for different NodeJS versions.

Implementation is feature equivalent to meichlseder/ascon-py.git, including known answer tests for all supported ciphers.

Hi,

Thanks for sharing your implementations!
We've now updated the repository to include third-party implementations in README.md, and included both your repositories there.
