6502X: According to the datasheet, RDY must be high in order for interrupts to trigger
...
- this has implications for C64, as it may cause VIC interrupts to fire quite later than they currently do

* Use generic interface type on MOS 6052X for talking to the emulator core
* Change CpuLink constructors to not use expression-bodies, to get the AppVeyor build to pass.
* Add comment explaining why IMOS6502XLink exists.
