Possible memory issue with uploading large files using streams

[Lunatic174]

Problem Description

In version 4.0.6 of the jira.js library, uploading large files using ReadableStream has become less optimal due to increased memory consumption. The current implementation converts the stream into a Blob or File, which requires the entire file to be loaded into memory before it can be sent as a form attachment. Previously, with form-data, streaming files directly was supported without this intermediate step, avoiding unnecessary memory overhead.

Issue

The current implementation of the _streamToBlob method involves loading the entire file into memory (via Uint8Array[]) to construct a Blob. This approach is inefficient and can potentially cause the process to crash for large files.

With form-data, it was possible to append a Readable stream directly to FormData, which eliminated the need for loading the entire file into memory. However, formdata-node does not natively support this feature. That said, the maintainers of formdata-node provide examples (examples №8 and №9) for working with streams in the new version, which might help address this issue.

Open to Discussion

If there's a better or more efficient way to handle this use case, I would be happy to learn and discuss potential solutions.
