JSDOM initialization conflict

[tsapmic]

GPXparser initialize jsdom when it finds that module is not defined:

if(typeof module !== 'undefined'){
    require('jsdom-global')();
    module.exports = gpxParser;
}

In case if dom will be configured somewhere else it could cause conflicts.

In my case: I have a Vue application using GPXParser and running tests with vitest causing double jsdom initialization.

Could you please change it to something like this:

if(typeof module !== 'undefined'){
    if (typeof document == 'undefined') {
        require('jsdom-global')();
    }
    module.exports = gpxParser;
}
