Comment:
@ericonr: thanks for merging #29997.  What about this one next? It's an itch I have, since I use pari-gp a lot (literally daily, for my work).

I know this includes several changes, but there are 6 different optional data packages and all templates follow the same structure. Each change is documented in the respective commit as a bullet list.

Besides `pari-elldata` update and adding two new packages (always with the same template structure), the only thing that changes in the installed files is that datafiles are compressed when it makes sense (for files larger than 4k) saving a lot of installed-size.  For large packages a `<PKG>-small` package is split out which contains a reasonable minimal portion of the database (e.g. enough to pass tests) but installing `<PKG>` after this is equivalent to installing `<PKG>` before this.

Note that @dkwo and @motorto already reviewed this PR and gave :+1: above. Nothing changed here since then other than rebasing for pari updates.
