Gatling 3.13 compatibility

[aristotelous-perivola]

Hello, I would like to know if the plugin is compatible with gatling 3.13.X version. I am using gatling with java and i am following this example:
https://gatling.io/blog/kafka-load-test.

When i try to launch the simulation with mvn gatling:test I get some errors that might be attributed to version mismatch:

Note: I've provided a PR for upgrading but it wasn't merged: #14

[RussGarratt]

Have also submitted a PR (using Gatling 3.13.5) - but it may be a bit more of a longer review than the above
@slandelle -> did you not have to add the runtime opts for add-opens?

Found I had to in: #23
