fix comparison of COMP data

[yutaro-sakamoto]

This pull request fixes the comparison process of COMP data.
With older versions, comparisons of COMP data are invalid in some cases.

       identification division.
       program-id. prog.
       data division.
       working-storage section.
       01 u9 pic 9(9) comp.
       01 s4 pic s9(4) comp.
       procedure division.
       move 2 to u9. move -3 to s4.
       if u9 <= s4 then display "ng" end-if.

Changes

• Add a new method cmpInteger in AbstractCobolField
• Modify cobj/ to use cmpInteger when comparing COMP data
• add test suite in tests/data-rep.src/binary.at
• Add @deprecatred cmpInt and cmpUint because these functions should be cmpInteger.

"cmpU8Binary"のようなエンディアンに対応する関数は、Javaの保守性を考慮し、".getDecimal()"のような関数内で実装する方針としましょう。

I checked and there is no problem.

In consideration of the maintainability of Java, let's implement functions that support endianness such as "cmpU8Binary" within functions such as ".getDecimal()".
