Just wanted to add defocus blur but ended up changing a bunch of other
this as well.
- Moved scenes to a separate folder.
- Updated readme with more pretty images.
- Add interface for loading scenes. There is currently one for yaml
and another if you want a slightly random scene.
- Add image action to decide what to do with the final image once its
rendered. Currently supports just showing the buffer until you press
the render buffer again and saving the image as `png`.
- When you use nix shell you will be dropped in the proper folder so
you can just do cargo build etc without having to do `cd`.

- Set position of camera.
- Set look position of camera.
- Set FOV

Once the render is done it saves an PNG.

Refactored how the threading worked. Before it just keept up splitting
the screen recursively for x number of times.
Felt like using recursion was unnecessary. It's now just done in a
loop instead. The user can control the behaviour by setting
`num_threads_width` and `num_threads_height` which will split the
image x number of times and run a thread for each.
Split up the rendering function for one that does scaling and one
that doesn't. I just don't want to deal with any kind of scaling when
actually rendering the image. The code shouldn't change much so
maintaining is going to be ok.
- Fixed scaling issues where black bars would appear if the subimage
size wasn't divisible by the scale.
- Cleaned up a bunch of arcs and other things that wasn't neccesary
any more.

- Preview quality is crude but works good enough.
- Add scaling to render function. This helps to make the preview
faster because we can use the same result for several pixels.
- You can move around the camera a bit with wasd, super basic.
- Press R to start/stop rendering the scene.
|
|
- Made the traits into supertraits so we don't have to mention Send and
Sync everywhere.
- Add methods for Vec3 that modifies the existing Vector. Can be used
to make less copies.

- All data shared between threads are now Arcs since the data is
immutable.
- Remove tokio
- Rustified main
|
|
- Created a trait for all geometry that has to implement a hit
function. Depending on if the ray hits or not it returns an option
with the color.
- Add support for multiple samples per pixel
Current issues:
- Using cooperative multitasking which isn't that
helpful in this situation since it's like running without async but
without overhead. Should switch to rayon.
- All data gets copied once per job. Will decide later what to
do (copy or put locks and share data between jobs).

Creating a bunch of futures that when completed get the buffers copied
to the screen buffer updating the screen as it gets done.
It's a bit overkill to create a future per row but it can be changed
later.
Moved hsv_to_rgb to utils. Don't even think it will be needed later.
