Japes: a high troughput ecs. bevy style

“We” managed to track down the last not EA’d part of the UnifiedDelta benchmark. Allocation went from 2.3mb to 297kb / tick during while session. Troughput increased only marginnaly. This specific bench was written against a zayes implementation which also allocates nearly exactly the same 2.3mb. It does not follow exactly the zay-es pattern, but this is the fastest solution i managed to write. Without the EA trick zay was faster by a lot and now i would say the api overhead is the same.
