Hang for queries which return many overflow pages

[PThorpe92]

As part of testing my ongoing WAL work, I have been frequently inserting things like

insert into products(name,price) values (randomblob(1024*512),randomblob(1024*512));

many times in succession due to the need to generate wal frames.

Perhaps it's just the size, but sqlite seems to handle it fine, but if we do

select * from users, products limit 1000;

Currently tursodb will hang for this query, assuming we have done those inserts more than a couple times.

from the very limited testing i've done so far, this isn't a "hang" in the sense of an infinite loop, but instead a "hang" in the sense of being unbelievably slow
in any case, sqlite certainly doesn't print out the whole half megabyte blob on screen
I wonder if us not doing this is part of it #2304

like if we just had a reference to the payload then we could lazily print out the first 200 bytes of a column in the CLI or whatever, without ever cloning it fully
