Reorganize Directories

[elalish]

Replacing #156; see commentary there. The idea is to make the project's structure more clear by changing from our current layout:

root/
|--- docs/
|--- collider/
|--- manifold/
|--- meshIO/
|--- polygon/
|--- samples/
|--- test/
|--- third_party/
|    |--- assimp/
|    |--- glm/
|    |--- google_test/
|    |--- graphlite/
|    |--- pybind11/
|    |--- thrust/
|--- tools/
|--- utilities/

To this:

root/
|--- docs/
|--- bindings/
|    |--- python/
|    |    |--- examples/
|    |    |--- third_party/
|    |    |    |--- pybind11/
|    |--- wasm/
|    |    |--- examples/
|--- samples/
|--- extras/
|    |--- ...tools
|--- src/
|    |--- collider/
|    |--- manifold/
|    |--- polygon/
|    |--- utilities/
|    |--- third_party/
|    |    |--- glm/
|    |    |--- graphlite/
|    |    |--- thrust/
|--- test/
|    |--- meshIO/
|    |--- ...original tests, referencing examples
|    |--- third_party/
|    |    |--- assimp/
|    |    |--- google_test/

@pca006132 I mostly got the CMake stuff fixed, but I'm having trouble building Assimp (it can't seem to find the paths it wants). Since you got a lot of that working, would you mind taking a look?

[pca006132]

diff --git a/test/CMakeLists.txt b/test/CMakeLists.txt
index 00048bc..070ccd8 100644
--- a/test/CMakeLists.txt
+++ b/test/CMakeLists.txt
@@ -5,7 +5,7 @@ add_subdirectory(meshIO)

 add_executable(${PROJECT_NAME} ${SOURCE_FILES})
 target_link_libraries(${PROJECT_NAME} polygon GTest::GTest manifold meshIO samples)

The old one will recursively include all code in assimp and google_test, and tries to compile them with our compilation options (which does not work).

Thanks for the pointer @pca006132! I decided to keep samples instead of renaming it examples, mostly because I have deployed GLB models there and I don't want to break those paths. Do you have any idea why check_format is failing? I swear it worked once after I updated it, but now it just unhelpfully says it can't find a file.

[elalish]

Nevermind, I switched to a github action for format checking; simpler and it's working.
