feat: Improve React Native compatibility and bump version to 1.1.1

- **src/ledger.ts**:
  Updated the method of importing `ledger-bitcoin` to improve compatibility with React Native's Metro bundler. Replaced the dynamic import (`await import('ledger-bitcoin')`) with a direct `require` statement to mitigate bundler issues.

- **package.json & package-lock.json**:
  Bumped the version from 1.1.0 to 1.1.1 to reflect the improvements.

- **CHANGELOG.md**:
  Documented the changes made for version 1.1.1, highlighting the adjustment in importing `ledger-bitcoin` for React Native compatibility.

+## [1.1.1] - 2023-10-12
+
+### Changed
+
+- **React Native Compatibility**:
+  - Adjusted the way the library imports `ledger-bitcoin` in `src/ledger.ts` to improve compatibility with React Native projects using the Metro bundler.
+    - Previously, the library utilized dynamic imports (`await import('ledger-bitcoin')`), but this approach caused issues with Metro bundler. The bundler tried to unconditionally require `ledger-bitcoin` even if it wasn't installed (since it's an optional peerDependency).
+    - The new approach bypasses this by using a direct `require` statement. For more details on the underlying issue, refer to [this React Native discussion](https://github.com/react-native-community/discussions-and-proposals/issues/120).
+    - This update ensures smoother integration for developers using this library in React Native projects.
