/**
* Parser that reads in bytes from an InputStream, buffering them in memory
* until a `reset` call discards them.
*
* Mostly the same as ByteArrayParser, except using an UberBuffer rather than
* reading directly from an Array[Byte].
*
* Generally not meant to be used directly, but via [[ujson.Readable.fromReadable]]
