Starting on implementing different variants (#88)
* 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
