[supabase-js] async iterators for select

[almosnow]

Hi,

I've been using async iterators for everything lately, I think they help one write very clean code,

It would be nice if we could do something like:

for await(const record of supabase.from(TABLE).select()) {
  // ...
}

... and let it handle pagination and all other stuff transparently.

Does this already exist, btw?
