Send headers for encryption (Amazon S3)

[javdl]

To use encryption at rest on AWS S3 it is necessary to send headers like so:
x-amz-server-side-encryption AES256
https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingServerSideEncryption.html
Is it possible to set these with Meteor Slingshot? @koszta

@Joostvanderlaan just in case you're still looking for this functionality, it has been discussed before e.g. in #111 but unfortunately the PR was never merged. I needed this functionality too and created a fork and atmosphere package that include PR #111 which you can use if you like: https://atmospherejs.com/jamiesoncj/slingshot
