feat: add in_ filter on stream()

[dshukertjr]

What kind of change does this PR introduce?

Add support for the in filter to be used in .stream(). Same as the postgrest in_ method, in is a reserved word in Dart, so had to change the filter from in to in_.

supabase.from('table').stream(primaryKey: ['id']).in_('name', ['Andy', 'Santiago', 'Holt']).listen();

I think we need some additional " in case currentStreamFilter.value is a List of Strings containing , itself. I don't know how the realtime server handles them, but maybe do it like here?

I have updated the code, and did some testing. It works with int and basic string not containing ,, but it doesn't work with strings containing ,.

We could say it's a but on the realtime engine, but Supabase relatime isn't designed to cover every single query use case. If someone is trying to listen to values on the database with applying filters on a value with , in it, I'd say that particular person is doing something wrong.

We can keep the code in case Realtime engine does become compatible with , values in the string, but we shouldn't stress too much about it.

Have you considered inFilter or filterIn? I kinda find in_ weird

Great point! I have updated the code. We probably could update the name on postgrest methods too huh?
