feat: Add Python scripts to automate DCP and linear profile generation

[leyyce]

Summary

This PR introduces two interactive Python scripts to automate profile generation and deployment for any camera model supported by Adobe Standard profiles, along with updated documentation and .gitignore entries.

Changes

• create_profiles.py:
  • Automatically detects local Adobe Camera Raw profile directories across Windows and macOS.
  • Interactive CLI to search and select the base Adobe Standard.dcp for the user's camera model.
  • Batch compiles native Fujifilm DCP profiles by stripping existing LookTables, injecting curves from xml tables/, and applying required tags (DefaultBlackRender=1, ProfileLookTableEncoding=1).
  • Provides an optional one-click installation directly into the user's CameraRaw profile directory.
• create_linear.py:
  • Generates the camera-specific linear base profile (<Camera> Linear.dcp) required for applying the included 3D LUTs in Adobe Camera Raw.
  • Inserts a strictly linear 1:1 diagonal ToneCurve, strips LookTables, and sets DefaultBlackRender=1 to disable Adobe's default black clipping.
  • Prompts to deploy directly into CameraProfiles/Linear Profiles.
• Clean Temp Directory Management:
  • Both scripts utilize Python's tempfile.TemporaryDirectory() to ensure isolated decompilation and compilation without leaving build artifacts in the repository working directory.
• Documentation & Git Hygiene:
  • Updated README.md with script usage, prerequisites (dcpTool and PATH setup), and workflow descriptions.
  • Added .gitignore rules for output/, local dcpTool binaries, and temporary files.

Testing

• Verified profile decompilation and recompilation with dcpTool (on Windows).
• Confirmed profiles load correctly in Adobe Lightroom Classic and Adobe Camera Raw with correct curve application.

create_linear.py:179

• The no-install branch prints user_profiles_dir, but the automatic branch installs into user_profiles_dir / "Linear Profiles" and the README documents that subdirectory. Following this manual instruction places the profile in the wrong location, so Camera Raw may not load it as the linear base.

        print(f"\nManual installation: Copy '{target_dcp.name}' to:\n{user_profiles_dir}")

create_linear.py:26

• The non-Windows/non-macOS branch is also the Linux path, but it never checks an Adobe profile location: it searches only the current directory and installs under the repository's installed_dcp folder. That makes the advertised cross-platform detection/deployment fail on Linux; add a supported platform-specific location or require an explicit override instead of silently treating the working directory as Adobe's directory.

    else:
        base_search = Path.cwd()
        user_profiles_dir = Path.cwd() / "installed_dcp"

create_profiles.py:188

• Compilation failures are only printed and do not affect the final success path: the script still reports "Build complete" and then deploys every existing *.dcp in the output directory. On a rerun, a failed look can therefore install a stale profile from an earlier run, while a partial build is presented as complete. Track the outputs and failures for this invocation and abort or install only successful current outputs before offering deployment.

            if compile_res.returncode == 0 and target_dcp.is_file():
                print(f"  [OK] '{display_name}' -> {target_dcp.name}")
            else:
                err_msg = (compile_res.stderr or compile_res.stdout).strip()
                print(f"  [FAILED] {target_dcp.name}: {err_msg if err_msg else 'Unknown error'}")
