REDIM, TYPE, and STRING Woes

[DSMan195276]

Save to a second file (say *.vlsd for variable length string data) and only have the main file store offset + size.  

I don't personally consider that a viable fix because writing UDTs to a file shouldn't result in other files being created IMO it just creates too many potential problems. Storing them all in a single file also has separate issues because any reorganization of them would require modifying all the `offset + size` entries, and we don't know where they all are.


The GitHub issue for the redim thing is here.
