Enhance the ToString method to display the underlying integer for enums instead of the prop name

[ahmad-moussawi]

public enum Type {
  A,
  B,
  C,
}

var query = new Query("Table").Where("Type", Type.A);
var sql = compiler.Compile(query).ToString(); 

Current behavior

// SELECT * FROM "Table" WHERE "Type" = 'A'

Expected behavior

// SELECT * FROM "Table" WHERE "Type" = 0

Is there any way to switch back to the prop names behavior? I know I can always do like that Where("Type", Type.A.ToString()), but my project stores enums as strings, so I never store enums as integers.
