[WIP] Add a condition of camel case detection

[chansuke]

Fixes #4639.

I simply added a condition to camel_case util to pass IData type of word but I'm not sure this is the right approach..

@chansuke Let us know if you need any help =)

@phansch Thanks for your help!! I probably misunderstanding the way to detect the IData type of camel case. I simply thought that I could solve the issue by appending a condition to if c.is_uppercase() but I think it's wrong. Can you give me any suggestions for an another approach?

[chansuke]

@phansch Sorry again, I am trying to detect IData with below condition

if c.is_uppercase() && !s.chars().nth(i - 1).unwrap().is_uppercase() {}

but is this a good approach to solve the problem?
