Flip test directory structure 🔃

Move full/lang/library to the top-level as that's more ergonomic to use.

-Directory structure:
+Top level directory structure:
+- `full`: Tests of full documents.
+- `lang`: Tests for specific language features.
+- `library`: Tests for specific library functions.
+- `res`: Resource files used by tests.
+
+Directory structure for each category:
 - `typ`: Input files.
 - `ref`: Reference images which the output is compared with to determine whether
          a test passed or failed.
-- `res`: Resource files used by tests.
 - `png`: PNG files produced by tests.
 - `pdf`: PDF files produced by tests.
 
-The test files are split into three categories:
-- `full`: Tests of full documents.
-- `lang`: Tests for specific language features.
-- `library`: Tests for specific library functions.
-
 To keep things small, please optimize the reference images:
 ```bash
 # One image
-oxipng -o max tests/ref/image.png
+oxipng -o max path/to/image.png
 
 # All images
-oxipng -r -o max tests/ref/*
+oxipng -r -o max tests/*/ref
 ```
