Mining (#95)

* more mining stuff

* initialize azalea-tags crate

* more mining stuff 2

* mining in ecs

* well technically mining works but

no codegen for how long it takes to mine each block yet

* rename downloads to __cache__

it was bothering me since it's not *just* downloads

* codegen block behavior

* fix not sending packet to finish breaking block

* mining animation 🎉

* clippy

* cleanup, move Client::mine into a client extension

* add azalea/src/mining.rs
