Make SupabaseQueryBuilder generic

[programmador]

PostgrestQueryBuilder is generic while it's descendant SupabaseQueryBuilder is not.
As a consequence the only available result type is dynamic while actually under the hood it's predominately List<Map<dynamic>> or even List<Map<String,dynamic>> which could be determined while debugging (though I have no idea what _JsonMap is).

Could it be implemented as generic? Moreover there is postgrest-dart 0.2 where PostgrestQueryBuilder is a descendant of Future (which is also generic).

Any Update Regarding ? handling

We now have this supported thanks to supabase/postgrest-dart#94

You can use it like this:

// data is `List<Map<String, dynamic>>`
final data = await supabase.from('users').select<List<Map<String, dynamic>>>();

// data is `Map<String, dynamic>`
final data = await supabase.from('users').select<Map<String, dynamic>>().eq('id', myId).single();
