missing uploadPartCopy?

[AlJohri]

looks like when doing a client.createMultipartUpload if I am uploading the parts using a copy via client.uploadPartCopy I get an exception. seems like only multipart upload is implemented. i think this is the offending line:

s3mock/src/main/scala/io/findify/s3mock/route/CopyObjectMultipart.scala

Line 44 in 068a585

val byteSeq = req.getHeader("x-amz-copy-source-range").get().value()

Traceback:
