Setting near and far with scene bounds collider. Also LR schedules. (#74)

* some initial cuda code as I learn. using git to save progress.

* first cuda kernel for ray sampling that mostly works

* cleaning up code. working on lr. structs for scene bounds aabb

* added scene bounds collider code

* updated setup

* setup

* setup

* black

* including some files

* exporting env variable

* new file

* git workflows

* github actions

* github actions

* github actions

* removing env var
