HTTP Headers of PATCH Blob Chunk uploads do not match OCI Spec

[containerdude]

Hi,

I'm seeing some instability with nodejs-container-image-builder and blob uploads against AWS ECR. I believe that this may be because the library is not quite spec compliant. This results in requests that sometimes succeed and sometimes fail - not good in my CICD pipeline.

I call image.addFiles({'target/':'src/'}) and it appears that the underlying PATCH call that this generates matches OCI spec endpoint end-5.

Per the spec, the following request headers are mandatory:

Content-Type: application/octet-stream
Content-Range: <range>
Content-Length: <length>

However it seems that only Content-Type is actually sent with the request.

I would be grateful for any assistance in getting this resolved. Unfortunately job constraints preventing me from signing any CLA around this.
