Dropped support for fetching objects and non-zero column

1. `FetchMode::STANDARD_OBJECT` and `FetchMode::CUSTOM_OBJECT` are no longer supported. 2. `FetchMode::COLUMN` with a non-zero index is no longer supported. 3. Incompatible change in the `Connection::fetchColumn()` signature where the 3rd argument is now `$types`, not `$columnIndex`.

 # Upgrade to 3.0
+## BC BREAK: Dropped support for `FetchMode::CUSTOM_OBJECT` and `::STANDARD_OBJECT`
+Instead of fetching an object, fetch an array and map it to an object of the desired class.
+## BC BREAK: Dropped support for the `$columnIndex` argument in `ResultStatement::fetchColumn()`, other `ResultStatement::fetch*()` methods invoked with `FetchMode::COLUMN` and `Connection::fetchColumn()`.
+In order to fetch a column with an index other than `0`, use `FetchMode::NUMERIC` and the array element with the corresponding index.
 ## BC BREAK: Removed `EchoSQLLogger`
 `EchoSQLLogger` is no longer available as part of the package.
