fix: accessibilityIgnoresInvertColors prop not recognised when using …

…TypeScript (#666)

 - in testing [eslint-plugin-react-native-a11y](https://github.com/FormidableLabs/eslint-plugin-react-native-a11y) with `react-native-fast-image`, I noticed that a11y props such as `accessibilityIgnoresInvertColors` are missing from FastImage's TypeScript definitions
- in theory the "proper" fix for this would be to make `FastImageProps` extend `ImagePropsBase` from React Native, because ultimately FastImage [spreads Props down](https://github.com/DylanVann/react-native-fast-image/blob/master/src/index.tsx#L150-L160) to React Native's Image component (including a11y props)
- attempting this "proper" fix proved problematic in practice due to incompatibilities between the two interfaces
- instead rather than extending the entirety of `ImagePropsBase` (which itself extends `AccessibilityProps`) we can resolve this by simply also extending `AccessibilityProps`
