Version 0.16.4 Released - Occurrent - Event Sourcing Utilities for the JVM

Occurrent 0.16.4 is released with the following changes:

Added a kotlin extension function that makes it easier to execute a RetryStrategy with a “Supplier”.

The reasons for this is that when just doing this from kotlin:
```
  val string = retryStrategy.execute { "hello" }
```
This will return Unit and not the “hello” string that you would expect. This is because execute in the example above delegates to org.occurrent.retry.RetryStrategy.execute(java.lang.Runnable) and not org.occurrent.retry.RetryStrategy.execute(java.util.function.Supplier) which one would expect. Thus, you can use this function instead to avoid specifying the `Supplier` SAM explicitly.

I.e. instead of doing:
```
    val string : String = retryStrategy.execute(Supplier { "hello" })
```
you can do:
```
    val string : String = retryStrategy.exec { "hello" }
```
after having imported org.occurrent.retry.exec.
Kotlin jvm target is set to 17

Added ability to map errors with RetryStrategy, either by doing:

retryStrategy
            .mapError(IllegalArgumentException.class, IllegalStateException::new)
            .maxAttempts(2)
            .execute(() -> {
                throw new IllegalArgumentException("expected");
            }));

In the end, an IllegalStateException will be thrown. You can also do like this:

retryStrategy
            .mapError(t -> {
                if (t instanceof IllegalArgumentException iae) {
                    return new IllegalStateException(iae.getMessage());
                } else {
                    return t;
                }
            })
            .maxAttempts(2)
            .execute(() -> {
                throw new IllegalArgumentException("expected");
            }));

Added a new execute Kotlin extension function to the ApplicationService that allows one to use a java.util.UUID as a streamId when working with lists of events (as opposed to Sequence).
