"""Launcher for the idatui TUI.

  # attach to the single open session on a running server
  python -m idatui.tui

  # attach to a specific session
  python -m idatui.tui --db 80d83396

  # open (or reopen) an arbitrary binary, then drive it
  python -m idatui.tui --open /path/to/binary

The server (supervisor) must already be running (see spawn.sh). --open creates a
session via idb_open; the binary's directory must be writable (idalib writes a
.i64 next to it).
