* [wip] short_id implementation (first attempt)
todo - make this more reusable (a trait?) so we can use it for inputs/outputs/kernels easily
* factor short_id support out into ShortIdentifiable trait
* block can now be converted to compact_block
rename existing block.compact() -> block.cut_through()
* expose compact block representation via block api endpoint
optional with ?compact query param
