Fetch cost of current print via API

[zachstence]

Hi @OllisGit , great work on the project. I love this plugin and SpoolManager.

I'm working on showing data about the current print in a dashboard, and I am looking to get the cost of the current print via some API endpoint. I am using the API endpoints in SpoolManager to get the selected spool, but don't see any similar endpoints in CostEstimation.

I noticed here that the cost data is being sent/saved somewhere (/storeCurrentCosts). I looked through the code but can't find where that endpoint is, or what it does.

Is there any way to get this cost value externally? Thanks!
