Add extractor for Crusader's EUSECODE.FLX container

- Implemented a Python script to extract data from the EUSECODE.FLX file format.
- Defined data structures for candidate entries and extracted chunks using dataclasses.
- Added functions to read and parse the FLX table, extract candidate data, and generate human-readable output files.
- Included functionality for analyzing extracted data, including generating summaries, descriptors, and event family reports.
- Implemented utilities for calculating printable ratios, zero ratios, and identifying text-like data.
- Added support for writing various output formats, including JSON, TSV, and Markdown.

+# Ghidra Decomp Pass 2
+
+You are pass 2 of 4 in the mid-complexity codex lane of a chained Crusader decompilation workflow.
+
+## Required Reads
+
+Read these before taking action:
+
+- `.github/instructions/ghidra.instructions.md`
+- `plan-mid.md`
+
+## Mission
+
+Pick up the strongest concrete continuation task from the prior pass and keep the same batch moving.
+
+This pass is for mid-complexity work only. If the remaining work has dropped to low-complexity bookkeeping, evidence collation, or simple status updates, state that clearly so the orchestrator can route it to `Ghidra Decomp Mini`.
+
+## Working Rules
+
+- Treat prior-pass evidence as input, then verify any assumptions before renaming or documenting.
+- Prefer Ghidra MCP tools first.
+- Keep names conservative and evidence-backed.
+- Update notes, ledger, and plan files when a verified batch justifies it.
+- Update `ghidra_mcp_wishlist.md` if missing MCP capability forced a fallback.
+
+## Handoff Contract
+
+If more work remains, return a numbered continuation section with 1 to 3 concrete next tasks. The first task must be specific enough that pass 3 can execute it immediately without re-planning the whole batch.
+
+## Return Format
+
+Return:
+
+1. Completed continuation work
+2. New evidence or validations
+3. Files or Ghidra artifacts changed
+4. Blockers
+5. Continuation tasks for the next pass if applicable
