Fix pre-commit failures on main

[joyvelasquez]

typos and the whitespace/line-ending hooks were failing on the test data added in #23 and #24 (for example, typos flags the PARM mnemonic in the .blk files). The pre-commit.ci autofix also rewrote those data files' line endings.

This PR:

• Excludes tests/data/ from all pre-commit hooks, since those are original mission files that shouldn't be reformatted or spell-checked
• Moves a ruff:ignore[PLW2901] in get_layout onto the line it applies to, fixing a ruff-check failure on main

Needed for #30 to pass pre-commit.ci.

@namurphy This fixes the pre-commit.ci failures on main from the test data in #23/#24 (typos flagging PARM in the .blk files, and autofix rewriting their line endings). It's needed before #30 can pass. Happy to adjust if you'd prefer a narrower exclude or a different approach for the data files. Things got really messy with running black.

Thank you for cleaning up after me! I merged a few pull requests a little too quickly, it appears. 😅

Excluding tests/data/ from pre-commit is a good idea since the directory is for sample files from the current pipeline. 👍🏻
