Add support for java records

[tymur-berezhnoi]

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:

com.poiji.exception.PoijiInstantiationException: Cannot create a new instance of com.model.MyRecord

Hey @t-jd ,

Thanks for the issue, Poiji does not support new features of Java.

[tymur-berezhnoi]

Hi @ozlerhakan
Yep, but anyway, any plans to support new features like java records? It would be super useful if can bind xls row with a java record

[ozlerhakan]

It would be good to support indeed @t-jd

Hi @t-jd ,

Do you want to make this changes by yourself in the next release of Poiji? wdyt :)

[tymur-berezhnoi]

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

[ozlerhakan]

This will be ready in version 4.0.0 @t-jd Thanks!

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.
