Load stream events

[codeliner]

We should add two more methods to the event store interface:

• loeadStreamEvents
• loeadStreamEventsReverse

Both should be similar to loadAggregateEvents but only use the stream name as filter.
Instead of minVersion and maxVersion the methods should take skip and limit arguments so that clients can implement pagination logic while browsing a stream.

Hello @codeliner , I didn't realized that You had already assigned Yourself to this Issue when I created the PR 😞
But if You don't mind, I would really appreciate it if You would accept my PR. And if You would also label this Issue and/or the PR for Hacktoberfest, I would be very happy 😄

Hey @HolgerDoerner, thank you for your contribution. Yeah, I assigned the issue to myself as a reminder. Adding the methods to the interface is only half of the story ;) The real work needs to be done in the prooph/event-store bridge here: https://github.com/event-engine/prooph-v7-event-store/blob/master/src/ProophEventStore.php#L26

I can only merge your PR if the methods are implemented in the bridge ☝️ and some tests are added there, too.
prooph/event-store provides the functionality, so the bridge just has to translate. Should be straight forward. You can work on it, if you want. If you have questions, ask anytime. I don't have time at the moment to work on it myself.
