A React SVG icon component that renders an external link indicator arrow, commonly used to denote links that open in a new tab or navigate away from the current site.
## Key Components
**CustomExternalLinkIcon** - Main functional component that renders a customizable external link SVG icon
- **Props Interface**: `CustomExternalLinkIconProps` defining optional styling and dimension properties
- **SVG Paths**: Two path elements creating the external link arrow design
## Usage Example
```typescript
import { CustomExternalLinkIcon } from './custom-external-link-icon';
