Enhancement: support 'select' attribute of hxlocation

[krikkiteer]

Summary

According to the current htmx-docs, HXLocation supports an additional header 'select' which allows extracting elements of a response that shall be put into a given target.
This is currently not reflected in litestar-htmx's HXLocation.

It would be convenient to be able to use this like shown below as it extends coverage of htmx funcs in the plugin.

relevant htmx-docs can be found here: https://htmx.org/headers/hx-location/

Basic Example

return HXLocation(
    redirect_to=request.app.route_reverse("organisations:detail:contacts", org_id=org_id),
    target="#orgmain",  
    select="#orgmain",
    status_code=200,
)

Drawbacks and Impact

i can't see any drawbacks or incompatibilities that might arise, since its a completely optional parameter.

question is - should i make a pull-request for this ? and are there any aspects or requirements for tests i did miss ?
