Sets whether or not the parser's underlying stream is persistent.
If persist is true, the parser will attempt to construct
messages/parts whose content will remain on disk rather than being
loaded into memory so as to reduce memory usage. This is the default.
If persist is false, the parser will always load message content
into memory.
Note: This attribute only serves as a hint to the parser. If the
underlying stream does not support seeking, then this attribute
will be ignored.
By default, this feature is enabled if the underlying stream is seekable.
