Introduce BinaryStream/BufferStream

[f1ames]

Feature description

Introduce BinaryStream similar to BufferStream from v4.

By default, each chunk flowing through the stream would be a single byte. The stream should allow manipulating binary data (grouping, splitting, parsing, shifting, etc). Also it should be possible to convert such stream into other types (most notably StringStream and DataStream).

Use case

Various file types transformations, parsing binary formats, binary data manipulation (images, videos, etc).
