Major changes: ```go type ScanFunc func(r *Record) error ``` * Simplify the callback func signature by removing `ScanStatus` * Leverage context for cancellation * Add custom error `SkipCheckpoint` for special cases when we don't want to checkpoint Minor changes: * Use kinesis package constants for shard iterator types * Move optional config to new file See conversation on #75 for more details
