fix: add number to source prop type to support require() assets (#40)

The source prop type now accepts number in addition to string and
{ uri: string }, matching React Native's require() asset resolution
which returns numeric asset IDs. The runtime handling via
Image.resolveAssetSource() already existed in parseSource(); this
change aligns the TypeScript types with that behavior.

Fixes #39
