prevent forcing download payment page because of Content-Type octet-stream

[gudix]

Hello

When I add a request I get this Headers

Content-Type: application/octet-stream
Etag: "16b8a68361b388c1-13ad"

Server: Python/3.6 aiohttp/3.8.1

I think the Content-Type octet-stream forces the download of the page and not showing the payment page.

Any Idea how to fix this? I think it should be possible with application/bitcoin-paymentrequest. But I don't know where to change this.

best regards
