The units is case insensitive, which means the `Kb`, `kB` and `KB` are equals to `kb(KiloByte)`. If the unit is not provided, it defauts to `b(Byte)`. And these is no a unit called `bit`.

I updated the code just now. The change is listed below.

1. Use the simple config `max-size`. If the `max-size` is not set or is set to zero, the binary file is not allowed, or the BinaryIssue is raised. If the `max-size` is set and is not zero, the binary file can't be larger than `max-size`, or the BinaryFileTooLargeIssue is raised.
2. Restore the BinaryIssue, which was removed mistakenly.
3. Only check the newly added or copied files. The modified or renamed  binary files won't be checked.
4. Fix the bug that the binary check is not enabled.

Thanks for taking the time to review.
