* start on separating 6502 variants from cpu itself
* add a single variant: the NMOS one
* get examples & tests running again
* Add the Revision A variant, one that has no ROR
* disable failing lint in build-time dependencies
* Variant with no decimal mode
* Revert "disable failing lint in build-time dependencies"
This reverts commit c87975e937.
* some doc comments
* specify the variant in unit test now the API has changed
