Reshape from wide to long and save to GDX

`gdxreshape()` formats the data to be saved in GDX into long format. It is imported from the gdxrrw package with a few improvements for performance and usability, since there is a risk of it being removed from the gdxrrw package in the future. We would like to thank the R GAMS team for this useful function.
