Correct the key and value encoding for the cache

* WIP redo how we parse and use modes

* test expanding, too

* WIP integrate new Mode/ParsedMode into rest of code

* First pass integrated new mode bits

* fmt

* clippy

* Remove mode we no longer support from test metadata

* Address nits

* Add ability for compiler to opt out if it can't work with some Mode/version

* Elide viaIR input if compiler does not support it

* Improve test output a little; string modes and list ignored tests

* Move Mode to common crate

* constants.mod, and Display for CaseIdx to use it

* fmt

* Rename ModePipeline::E/Y

* Re-arrange Mode things; ParsedMode in format and Mode etc in common

* Move compile check to prepare_tests

* Remove now-unused deps

* clippy nits

* Update fallback tx weights to avoid out of gas errors

* Update kitchensink weights too and fmt

* Bump default geth timeout to 10s

* 30s timeout

* Improve geth stdout logging on failure

* fix line logging

* remove --networkid and arg, back to 5s timeout for geth
