Add formulas @DocAuthorFields and @DocReaderFields

In our applications, we have lookup view column formulas like this to read a document's write access on the view level without the need to open the documents:

_authorfields:=@Trim(@Transform(

@DocFields; "fld";

@If(@Begins(fld;"a_") | @Begins(fld; "al_");fld;"")

));

_authors:="";

@For(i:=1;i<=@Elements(_authorfields);i:=i+1;

_authors:=_authors : @GetField(_authorfields[i]));

@Trim(@Unique(_authors))

This works because we use prefixes for different item names (a_ for single authors, al_ for author lists).

For applications where we cannot expect this item naming schema, this is no help.

Please add new formulas @DocAuthorFields / @DocReaderFields to make this work for all kinds of databases.
