StackTraceElement assertions #2647

Feature summary

I would like to be able to perform assertions on StackTraceElement objects, as well as arrays/lists of StackTraceElement objects. This enables testing exception handling logic for remote execution, as well as exception handling for proxies.

Example

var ex = assertThatCode(() -> doSomethingRemotely())
    .isInstanceOf(SomeRemoteCodeException.class)
    .stackTrace()
    .hasFrameSatisfying(frame -> assertThat(frame).hasClass("com.example.Whatever#doSomethingRemotely"));

...this should be relatively simple as StackTraceElements themselves are just POJOs with a few flat attributes on them.
