All block shapes & collisions (#22)

* start adding shapes

* add more collision stuff

* DiscreteCubeMerger

* more mergers

* start adding BitSetDiscreteVoxelShape::join

* i love rust :smiley: :smiley: :smiley:

* r

* IT COMPILES????

* fix warning

* fix error

* fix more clippy issues

* add box_shape

* more shape stuff

* make DiscreteVoxelShape an enum

* Update shape.rs

* also make VoxelShape an enum

* implement BitSet::clear

* add more missing things

* it compiles

W

* start block shape codegen

* optimize shape codegen

* make az-block/blocks.rs look better (broken)

* almost new block macro

* make the codegen not generate 'type'

* try to fix

* work more on the blocks macro

* wait it compiles

* fix clippy issues

* shapes codegen works

* well it's almost working

* simplify some shape codegen

* enum type names are correct

* W it compiles

* cargo check no longer warns

* fix some clippy issues

* start making it so the shape impl is on BlockStates

* insane code

* new impl compiles

* fix wrong find_bits + TESTS PASS!

* add a test for slab collision

* fix clippy issues

* ok rust

* fix error that happens when on stairs

* add test for top slabs

* start adding join_is_not_empty

* add more to join_is_not_empty

* top slabs still don't work!!

* x..=0 doesn't work in rust :smiley: :smiley: :smiley: :smiley: :smiley: :smiley: :smiley: :smiley: :smiley: :smiley: :smiley: :smiley: :smiley: :smiley:

* remove comment since i added more useful names

* remove some printlns

* fix walls in some configurations erroring

* fix some warnings

* change comment to \`\`\`ignore instead of \`\`\`no_run

* players are .6 wide not .8

* fix clippy's complaints
