breaking change: sys.set_irq() and sys.set_rasterirq() no longer have useKernal parameter! The irq handler routine must return a boolean instead in the A register.
When it returns true it means run the system IRQ handler afterwards. When it returns false, the system handler is NOT ran afterwards.

api change: renamed cx16.push/pop_vera_context() to save/restore_vera_context()
this better reflects its capability because it doesn't use a stack, only a single buffer
