fix: Somehow, test file changed line endings to CRLF. Changed it back to LF.

The method I was trying started to irk me when I thought of creating a test unit for it. Also fixed some other issues I found in the package_to_description function (SHA256SUM section still missing).

+The goal of this library is to be completely self-contained, meaning any

 ## Development
 
@@ -15,41 +18,13 @@ See the [source code](src) for the list of modules.
 Everything is handled by the provided Makefile. To compile the static library,
 simply run `make`.
 
-### Project structure
-
-Each module has its own subdirectory inside `src`, e.g. `src/cron`. This
-directory contains the actual implementation of a module, along with any
-internally used header files. Each internal function should be defined in a
-header file, as to make testing these possible.
-
-Each module should also have its own header file inside the `include`
-directory. This header file defines the public API that the library exposes for
-this specific module.
-
-Any code in a module may only import internal headers from that module, along
-with any of the public API header files. Modules should not depend on each
-other's internal implementationns.
-
-Each module should contain a README describing its contents.
-
-All file names, function names... (even internals) should follow snake case
-convention and have a prefix unique to that module, starting with `vieter_`.
-For example, the `cron` modules uses the `vieter_cron_` prefix for everything.
-
-Header files should only import what they explicitely need. If some function is
-only used in a .c file, the import should be placed in the .c file instead.
-
 ### Testing
 
 This library uses [Acutest](https://github.com/mity/acutest) for its tests.
 Tests should be placed in the `test` subdirectory, further divided into
-directories that correspond to those in `src`. Test files should begin with
+directories that correspond those in `src`. Test files should begin with
 `test_`, and their format should follow the expected format for Acutest.
 
-Each `test_` is compiled separately into a binary, linked with libvieter. A
-test file can import any of the public API header files, along with any header
-files defined in its respective module. This allows testing internal functions.
-
 To run the tests, simply run `make test`. If you wish to only run a specific
 test binary, you can find them in `build/test`.

-This min-heap implementation is a pretty standard binomial heap.
-
-## Representation in memory
-
-A heap consists of one or more binomial trees, each with a different order `k`
-and `2^k` total nodes. This heap can contain `2^64 - 1` elements at most, which
-is far more than your memory can contain, but it's still fun to mention.
-
-A tree does not have its own memory structure; a node that's the root of a
-binomial tree is simply called the tree.
-
-Each node has the following layout:
-
-```c
-typedef struct vieter_heap_node {
-    uint64_t key;
-    void *data;
-    struct vieter_heap_node *largest_order;
-    union {
-      struct vieter_heap_node *next_tree;
-      struct vieter_heap_node *next_largest_order;
-    } ptr;
-    uint8_t order;
-} vieter_heap_node;
-```
-
-Each node has a pointer to its child with the largest order (if the node's
-order is `0`, this pointer will be NULL). Each non-root node has a pointer to
-its sibling with the next-highest order. These pointers allow the children of a
-binomial tree to be recombined into a new tree, once their root has been
-pop'ed.
-
-Roots point to the binomial tree in the heap with the next largest order.
