unlist varsYZ for compatibility with upcoming data.table

[tdhock]

Hi @djhurio @JBreidaks
I see that vardpoor uses data.table::melt, which has slightly different behavior in the next planned release (currently on github only).
Using data.table from github master, we get an error when running vardpoor examples, Rdatatable/data.table#6071
To fix that error, please accept this PR (which should work with both the current version of data.table on CRAN, and on github).
After merging the PR, please submit an update to CRAN.
Thanks!

Dear @tdhock,
I am not working at the CSBLatvia any more. Neither is @JBreidaks.
I believe somebody from the CSBLatvia will respond on this.

Thanks for the quick response Mārtiņš !
I see you are still the CRAN maintainer, https://cloud.r-project.org/web/packages/vardpoor/
so if you no longer want to maintain vardpoor, it would be good if you could please find another maintainer, and ask them to submit the new version with their email as new maintainer to CRAN (and you will have to confirm to CRAN the change of maintainer).

I have delegated the maintenance of the package to @jvoronova (@jvoronova - is it correct?).
However, I don't own the e-mail address <martins.liberts at csb.gov.lv> any more. I believe it should have been deleted long time ago. I am not sure how can I confirm the change of maintainer in this case.

Thanks for the info! I think CRAN will accept a confirmation email from your new address.
