strom: fix generator for pointer-receiver Encode, use nbt.Tag for named NBT

- Delete raw_capture subcommand (use tcpflow + raw-to-tmcpr instead)
- Fix DefaultEncoder to use temp variable for non-addressable value encoding,
  eliminating manual post-generation patches
- Map nbt and optionalNbt types to nbt.Tag (named NBT) instead of nbt.Anon
  (anonymous NBT) — 1.8 uses named NBT with root tag names
