### `ColumnSelectionPlugin`

The `ColumnSelectionPlugin` is an essential plugin for RevoGrid, designed to enhance user interaction
by enabling column selection functionalities. It allows users to focus on and select entire columns,
facilitating workflows that require column-based data manipulation and analysis.

**Key Features**:
- **Column Focus and Selection**: Allows users to focus on specific columns, highlighting them
  for operations like data editing, copying, or analysis.
- **Event-Driven Architecture**: Listens to and dispatches various events such as `COLUMN_UPDATED_EVENT`,
  `EVENT_HEADER_FOCUS`, `EVENT_BEFORE_CELL_FOCUS`, and `EVENT_BEFORE_FOCUS_LOST` to manage column
  selection and focus logic effectively.
- **Dynamic Column Updates**: Adjusts selections based on column updates, ensuring that the active
  selection remains consistent with any changes in column configuration.
- **Integration with Selection and Data Stores**: Utilizes observable stores for managing selection
  states, interfacing with the grid's data and selection stores to apply and clear selections.
- **Header Interaction**: Reacts to header clicks to initiate column selection, allowing seamless
  user interaction with column headers.

**Usage**:
- Integrate this plugin into a RevoGrid instance to enable column selection features. Add the plugin
  to the grid's plugin array to activate its functionality.

### Example
```typescript
import { ColumnSelectionPlugin } from '@revolist/revogrid-pro';

const grid = document.createElement('revo-grid');
grid.plugins = [ColumnSelectionPlugin];
```

This plugin is ideal for applications where column-centric interaction is critical, providing
an intuitive interface for managing and selecting columns in complex data grids.

```ts
class ColumnSelectionPlugin {
  destroy(): void;
}
```
