Reconsider format for streamed types

[mp911de]

Streamed types are modeled with an unknown length. However, the individual chunk lengths are known. Defining an EOF marker and stream-parsing the EOF marker introduces a certain degree of complexity to clients.

Why we don't stick to a pattern such as partial length-prefixed chunks? Each chunk is prefixed with a length indicator (similar to strings) and a negative length value would serve for the EOF marker.

?10<CR><LF>
<10 bytes of data><CR><LF>
?400<CR><LF>
<400 bytes of data><CR><LF>
?-1<CR><LF>    <----- EOF marker

(using ? here as there was no other free character as a prefix for a stream response type).

Hello @mp911de, yep we are going in the direction you said, I had no time to update the spec but is similar to what you suggested. I'll try to update it shortly.
