4.5.0 modifyRequestHeader change causes TypeError when second parameter is absent

in reference to #3996

https://github.com/Dash-Industry-Forum/dash.js/blob/development/src/streaming/utils/RequestModifier.js

RequestModifier.modifyRequestHeader
old call was modifyRequestHeader(xhr)
same call with new prototype results in:
Uncaught TypeError: Cannot read properties of undefined (reading 'url')
at Object.modifyRequestHeader (RequestModifier.js:57:45)
A possible fix would be to set a default value as in:

modifyRequestHeader: function (xhr, {url}={}) { ... } in which url will present as undefined when not provided

or

modifyRequestHeader: function (xhr, {url=""}={}) { ... } in which url will present as empty string when not provided

Thank you for your consideration.

I dont quite understand how you call the Request Modifier. The standard approach would be like this: https://reference.dashif.org/dash.js/nightly/samples/advanced/extend.html . In this case you can omit the {url} if you want.
