Non-generic CRUD support

[Kayuse88]

Hi, I have several issue with some CRUD operation ex) CreateTableAsync.

My codes need to deal with dynamic type of T, but the generic type requires explicit type definition.

They use typeof(T) instead internally, but modifier limits to reuse these methods.

It'll be nice to add public non-generic CRUD methods.

Thanks for your support.
