Download button do not allow popup new download in separate tab

[luipir]

We had an issue integrating stac-browser in the PCKE infrastructure that we have to use. Due to issue/limitation, we want to override it opening download in a separate popup but the stac-broser do not do this in a https context.
The reason of this is that stac-browser is using StreamSaver.js here to allow stream download.

IMHO this behaviour should be configurable and do not force to remain in the same page opening an hidden iframe.

The issue is reproducible in HTTPS download where the StreamSaver.js create an hidden iframe to manage the stream. if context is not secure (e.g. http download), then a new tab is open to create secure connection.

I already open a feature request to StreamStream.js to add a configuration parameter to force or not iframe/popup use:

I was copletly wrong and no altDownload was used. instead the new popup was prevented by download property set to download="download" in:
https://github.com/radiantearth/stac-browser/blob/main/src/components/HrefActions.vue#L162

I'll prepare a PR to allow this disable by conf if I understand how configuration is propagated and accessed in each component.

I don't understand what the actual issue is here. Why would you want a popup?
