This adds some convenience accessors for getting dumps, messages, and matrices as separate entries from an invocation of `qsharp.run` and `qsharp.eval`. Previously, the only way to get a state dump from a run was the awkward:
```python
state = qsharp.StateDump(qsharp.run("DumpMachine()", shots=1, save_events=True)[0]["events"][0].state_dump())
```
This change preserves the existings "events" entry in the saved output, which has everything intermingled in the order from each shot, but also introduces dumps, messages, and matrices that will keep just the ordered output of that type. This makes the above pattern slightly better (and more discoverable):
```python
state = qsharp.run("DumpMachine()", shots=1, save_events=True)[0]["dumps"][0]
```
This adds similar functionality to `qsharp.eval` which now supports `save_events=True` to capture output, so for single shot execution you can use:
```python
state = qsharp.eval("DumpMachine()", save_events=True)["dumps"][0]
```
