/**
* A very fast streaming multipart parser for node.js.
* Dicer is a WritableStream
*
* Dicer (special) events:
* - on('finish', ()) - Emitted when all parts have been parsed and the Dicer instance has been ended.
* - on('part', (stream: PartStream)) - Emitted when a new part has been found.
* - on('preamble', (stream: PartStream)) - Emitted for preamble if you should happen to need it (can usually be ignored).
* - on('trailer', (data: Buffer)) - Emitted when trailing data was found after the terminating boundary (as with the preamble, this can usually be ignored too).
*/
