Remove rdf-canonize-native support

Remove all support for rdf-canonize-native bindings to simplify the
codebase and reduce maintenance overhead. The JavaScript implementation
provides sufficient performance for most use cases and eliminates the
complexity of native dependencies.

- Remove native package loading and initialization
- Remove useNative option and _rdfCanonizeNative API
- Remove native test cases from test suite
- Update documentation to remove native references
- Clean up package.json browser/react-native configurations

 # rdf-canonize ChangeLog
 
+## Unreleased
+
+### Removed
+- **BREAKING**: Remove all support for `rdf-canonize-native`. The JavaScript
+  implementation is now the only supported method. Native bindings support 
+  has been completely removed from the library, tests, and documentation due 
+  to limited performance benefits and maintenance overhead.
+
 ## 4.0.1 - 2023-11-15

-### Node.js + npm + native bindings
-
-This package has support for [rdf-canonize-native][]. This package can be
-useful if your application requires doing many canonizing operations
-asynchronously in parallel or in the background. It is **highly recommended**
-that you understand your requirements and benchmark using JavaScript vs native
-bindings. The native bindings add overhead and the JavaScript implementation
-may be faster with modern runtimes.
-
-The native bindings are not installed by default and must be explicitly
-installed.
-
-```
-npm install rdf-canonize
-npm install rdf-canonize-native
-```
-
-Note that the native code is not automatically used. To use the native bindings
-you must have them installed and set the `useNative` option to `true`.
-
-```js
-const canonize = require('rdf-canonize');
-```
