Changed

• Improved BinaryStream:
  getData([release]) now returns ByteBuffer, does not clear by default, and
  optionally releases data after reading; createPacket(pktid[,raw]) now
  supports raw packets; scalar read* APIs were added; several numeric
  write* APIs now accept String for BigInt-friendly input
  @zimuya4153
• Improved file and item behavior:
  File.readFrom(path[,isBinary]) now supports binary reads;
  File.writeTo(path, text) now accepts ByteBuffer;
  it.setLore([]) now clears custom lore instead of failing @zimuya4153
• Improved player NBT APIs:
  mc.getPlayerNbt(uuid) now returns Null when no saved data exists and can
  read online players directly; mc.setPlayerNbt(uuid, nbt[, forceCreate, isOnlineMode]) now supports optional offline record creation; player NBT
  APIs now validate UUID input more strictly @zimuya4153
• Improved NBT serialization:
  NbtCompound::toSNBT([space[,format]]) now supports explicitly selecting
  SnbtFormat; one-argument usage still defaults to SnbtFormat::ForceQuote
