Set request options via event in module

[andrewhawkes]

I need to set Authorization headers for a particular feed.
I understand you can set these headers within requestOptions in the feed-me.php config file.
However, this file gets loaded on every request and I need to request tokens etc. So I don't want this to happen on every request.

Ideally, it would be good if I could set these headers using an event such as beforeFetchFeed but it doesn't look like you can modify the request.

Any help would be greatly appreciated.
