Add mining to the pathfinder (#122)

* basic pathfinder mining poc

* mining descending and autotool

* pathfinder mining descending

* pathfinder fixes

* allow disabling pathfinder miner and other fixes

* small optimization to avoid chunk vec iter lookup sometimes

* seeded rng in pathfinder bench

* consistently use f32::INFINITY

this brings performance much closer to how it was before

* astar heuristic optimization from baritone

* add downward_move

* fix downward move execute

* avoid liquids and falling blocks when mining

* fix COST_HEURISTIC

* fix to not path through flowing liquids

* only reset pathfinder timeout while mining if the block is close enough

* cache mining costs of block positions

* fix mine_while_at_start and move PathfinderDebugParticles to its own module

* add ReachBlockPosGoal

in other news: azalea's sin/cos functions were broken this whole time and i never noticed

* clippy and add things that i accidentally didn't commit

* improve wording on doc for azalea::pathfinder
