Streams

[sppmacd]

• Split Reader into Text/BinaryReader and Writer into Text/BinaryWriter
• Implement:
  • MemoryStream
  • Socket (idk what to do with UDP here)
• Make writer's encoding not an element of its state (take it as argument where needed instead)
• TextReader methods:
  • OsErrorOr<Util::UString> read_until(char delim, Encoding e)
  • OsErrorOr<T> read_number<T>() (must read number or throws)
  • OsErrorOr<Util::UString> read_line(Encoding e) => read_until('\n')
  • OsErrorOr<void> ignore(char delim) => read_until(delim)
  • peek with strings
