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 1
+
+You are pass 1 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
+
+Execute the first focused work item in the batch.
+
+Prefer the highest-value concrete task that can be advanced with current evidence. Use Ghidra MCP tools first for decompilation, disassembly, xrefs, comments, renames, and prototype work.
+
+This pass is for mid-complexity work only. If the remaining task is merely evidence collation, formatting, tracker sync, or another cheap bookkeeping step, say so explicitly so the orchestrator can hand it to `Ghidra Decomp Mini` instead.
+
+## Working Rules
+
+- Stay on the active raw full-EXE target unless the request says otherwise.
+- Avoid speculative names.
+- Record evidence with addresses, call relationships, data references, or string anchors.
+- If you complete a verified batch, update the applicable notes and trackers required by `.github/instructions/ghidra.instructions.md`.
+- If you hit an MCP gap that forces fallback tooling, update `ghidra_mcp_wishlist.md`.
+
+## Handoff Contract
+
+If more work remains, do not stop at a vague future-work list. Return a numbered continuation section with 1 to 3 concrete next tasks. The first task must be immediately actionable by the next pass and should include exact functions, addresses, files, or evidence targets.
+
+## Return Format
+
+Return:
+
+1. Completed work
+2. Evidence
+3. Files or Ghidra artifacts changed
+4. Blockers
+5. Continuation tasks for the next pass if applicable
