Try ScalaJS over GraalVM

[etspaceman]

It might be possible to build kinesis-mock using scalajs instead of graal. There are some pros and cons to this. This would allow kinesis-mock executables to have easier cross-platform integration, as you would not need to cross-compile it for every single platform. A TLS server should also perform better in NodeJS rather than Graal. However, this would also likely lead to a larger executable and docker-image. And performance would be something to keep an eye on.

To do this, certain pieces would need to be rewritten so that all included dependencies are scalajs compliant. For example, the AWS SDK utilities are brought in for MD5 hashing. We would have to use a separate library or write our own hashing routine for this to work properly.
