   JIRA: [NEMO-176: Improve sequential read from 
disk](https://issues.apache.org/jira/projects/NEMO/issues/NEMO-176)
   
   **Major changes:**
   - Read whole data to read from file stream first and decode them later in 
`FileBlock`
   
   **Minor changes to note:**
   - Remove `limit` parameter in `InputStreamIterator` of `DataUtil` and make 
`DataUtil#deserializePartition` to limit the stream itself by the partition 
size.
   - Remove the assumption that "the source and destination parallelism of 
One-to-One communication is always 1" in `OutputWriter` and `InputReader`
   
   **Tests for the changes:**
   - Existing `DataTransferTest`, `BlockStoreTest` and other unit tests cover 
this change.
   - Existing integration tests also cover this change.
   
   **Other comments:**
   - N/A.
