Add option to completely disable flag rendering and SVG loading

[ScobarDen]

Hey!
I want to use react-international-phone without any country flag being rendered or loaded (not just hidden with CSS, but not present in the DOM and not loaded as SVG at all).

Currently, even with hideDropdown and countrySelectorStyleProps={{ buttonStyle: { display: 'none' } }} the flag SVG is still rendered and loaded inside the input.
There is no public prop like hideFlag or similar to prevent this.

Use case:

• Privacy: don't want to load any external SVGs/assets
• Performance: reduce bundle size and network requests
• UI: want a clean input without any flag or country indicator

Request:
Please add a prop (e.g. hideFlag or showFlag={false}) to completely disable flag rendering and SVG loading.

Workarounds tried:

• CSS hacks (just hides, but SVG still loads)
• No public API for custom input or flag component
• Forking/patching the library (not ideal)

Thanks!
