[Feature Request] Change media type

[Saveriu]

What feature or change would you like to see made?

The current media type in the Accept header is:
multipart/related; type=application/octet-stream; transfer-syntax=*

It seems that it should be:
multipart/related; type="application/octet-stream"; transfer-syntax=*

Why should we prioritize this feature?

With a Spring Boot backend, by default, all frames request are not valid (406)

we should make it configurable, can you create a PR for us? i think OHIF has this logic https://github.com/OHIF/Viewers/blob/1456a493d66c90c787b022256c9f2846afb115fc/platform/core/src/utils/generateAcceptHeader.ts
