Holds the stream and content stream objects for a part.
Note that streams are not explicitly closed or detached on destruction of the
PartSreamContainer by design: the passed StreamInterfaces will be closed on
their destruction when no references to them remain, which is useful when the
streams are passed around.
In addition, all the streams passed to PartStreamContainer should be wrapping
a ZBateson\StreamDecorators\NonClosingStream unless attached to a part by a
user, this is because MMP uses a single seekable stream for content and wraps
it in ZBateson\StreamDecorators\SeekingLimitStream objects for each part.

|public getBinaryContentStream(?string $transferEncoding = NULL) : ?Psr\Http\Message\StreamInterface|
Checks what transfer-encoding decoder stream is attached on the

Checks what transfer-encoding decoder stream and charset conversion
Returns the part's stream containing the part's headers, content, and
|public hasContent() : bool|
Returns true if there's a content stream associated with the part.
Resets cached encoding and charset streams, and rewinds the stream.

Attaches the passed stream as the content portion of this
The content stream would represent the content portion of $this->stream.
If the content is overridden, $this->stream should point to a dynamic

Sets the part's stream containing the part's headers, content, and
