Add support for java records

See original GitHub issue

It would be awesome to map an xls/xlsx record to a java record, like this one:

public record MyRecord(
        @ExcelCellName("Writing code")
        String writingCode
) {
}

… but currently Poiji throws an exception:

Hi @ozlerhakan I will take a look once I have free time, but I don’t promise, maybe someone else will do it before me

right now there are some limits to unable java records on Poiji. This does not mean that we don’t add it to Poiji, however, once we handle it, I re open this issue to integrate it.
