0.0.2

Release notes:

• Update {store, segment, log}::read() API to return the offset or position (where applicable) for the next record.
  This makes client code more ergonomic as they always know which offset to read from if they know the first offset.
• Removed leaky abstractions
  • Removed header_padded_record_length() from commit_log::store::common
  • Removed advance_to_offset() and offset_of_record_after() from
    commit_log::CommitLog. They were leaking implementation details.
