Fix: skip reading from compacted records

[niafly]

We experience this issue when replaying messages from a compacted topic. For readMessageV2 we actually can receive a batch response with zero header count so this fix will skip the batch until it meet a non-empty one.

This is currently the fix that we applied to our local forked repository we're using now, but we expect to get this merged to get up-to-date with the origin public repository.

Fixes #874
