Add custom headers to the XHR Request

[RossUK88]

I have a use case where I don't want to disable CRSF checking in my application and I want my API to resolve the current logged in user from their cookies that have been set.

I added 2 new settings to help achieve this, but set the defaults to be sensible so this should be a none breaking change.

I'm not sure if this is out of the scope of the package, and I realise my case is a bit of an edge case with how we are loading Scorm items but it solves my use case

Hi @jcputney , thanks for the great package. I just installed the latest version, which is v1.6.1, to use the xhrHeaders settings. But, unfortunately, it didn't work. I try to check to the package in the node_modules, and I couldn't found the code to append the xhr headers as shown here https://github.com/jcputney/scorm-again/blob/master/dist/scorm-again.js

I'm using
"react": "^17.0.2",
"scorm-again": "^1.6.1",

when I try to "manually" edit the package inside the node_modules, it works. So, I wonder why I didn't get the latest files even the latest version is already installed.

I install using npm btw in case you need the information.

[UPDATE]
I solve the issue by install directly from this github repo, like this:

"scorm-again": "git+https://github.com/jcputney/scorm-again.git"
