[Feature Request] xStreamBufferDiscard() macro to remove X bytes from a buffer

Is your feature request related to a problem? Please describe. Sometimes I use buffers/queues as backups for data that might be re-/needed just-in-case. When it is clear it is no longer needed, I want to discard X many bytes/elements from the buffer/queue.

Describe the solution you'd like A simple pop/discard function that simply advances the internal pointers of buffers/queues, defacto discarding what was before.

Describe alternatives you've considered Currently I have to manually create a temporary array on the heap, copy into it, then delete, which is inefficient.

Additional context Equally beneficial would be able to read any arbitrary segment of existing data/items in the buffer/queue, while keeping the data in the buffer. Although queues have a peek() functionality, it is limited, and it is totally missing for other primitives such as stream buffers.
