MengMengCode 22487dbb1f Add PC/SC backend support for USB SIM readers
- Implemented a new `unsupportedBackend` in `backend_stub.go` to handle unsupported platforms.
- Created a `Service` struct in `service.go` to manage interactions with smart cards, including session management and identity reading.
- Added methods for reading identity, checking readiness, and authenticating with USIM applications.
- Introduced a `scriptedCard` for testing purposes in `service_test.go` to simulate card responses.
- Defined necessary types and error handling in `types.go` for better clarity and usability.
- Developed a `PCSCAdapter` in `vowifi/pcsc_adapter.go` to integrate PC/SC service with Wi-Fi calling functionalities.
- Added a new SVG icon for USB SIM readers in `public/sim-reader.svg`.
- Implemented tests to ensure correct functionality and error handling in various scenarios.
