Prepared for releasing version 0.1.5

[otegami]

What I did

• Added changed codes and documentation to news.md by PR
• Updated Datasets::VERSION from 0.1.5 to 0.1.6

Notes for reviewers

Would you check the contents of news.md? And I really want to add what kou did to news.md but there were a lot of changed I couldn't write.

[kou]

We don't need to add notes for commits that aren't related to users such as expected value update in test. Because this is for users.
