General support for gpx extensions #54
Description
Description:
The current implementation of the library supports parsing a specific extension, but does not provide a mechanism to parse other extensions that can be found within the <extension> tag in a GPX file. This limitation restricts the library's flexibility and compatibility with GPX files that contain various custom or third-party extensions.
Expected behavior:
The library should parse all data contained within the <extension> tag, regardless of the extension's name or structure. The parsed data should be made accessible to users in a structured and user-friendly format, such as a map or dictionary. Users should have the ability to iterate through or query the parsed extensions and retrieve their values.
