feat: Add NFC support

[calganaygun]

Fixes #13

Adds NFC invoice/address sharing for Android.

Todos:

• Create a custom fork of react-native-hce, as the current library version does not fully support the latest NFC emulation standards. (Currently fixed it on node_modules, for development purposes). See Fixed: Unable to send NDEF message appidea/react-native-hce#35 (comment)
• Verify that the lightning: URI schema aligns with project requirements. This schema is currently supported by all wallet apps.
• Implement NFC status detection to check if NFC is enabled, with a popup or toast notification to remind the user if it is off.
