v1.13.0

[1.13.0] - 2020-09-10

This is a large release containing fixes and features from a multitude of contributors. Some notable changes:

• Dropped support for Node 8. Given that Node 8 was EOL in the beginning of 2020, for the overwhelming majority of people this should not be an issue.
• For Typescript users this release may require you to make minor changes, due to #764, which changes the type of KafkaMessage.value from Buffer to Buffer | null. This was in fact always the behavior at runtime, so this change is just fixing a bug in the types - but it will require you to handle the value being null for your project to build.
• Thanks to @ankon, we now support all the necessary functionality to enable Rack-Aware Follower Fetching to cut data transfer costs and reduce latency.
• Several changes to improve performance! Some larger initiatives, such as eagerly processing fetched batches in parallel, and some more contained optimizations such as reducing the amount of buffer copying during socket data buffering. We hope that these changes will have a noticeable effect on your applications, and look forward to hearing your feedback.
