Would be nice if the frontend could supply callbacks for the backend. Examples:

• Display is cleared
• Display is dirty
• Key is (not) pressed
• Sound is played

Depends on #12

Should return an Err to the loop instead.

Does it make sense to support this here?

Perhaps we should separate the actual opcodes from the underlying instructions, so it's easier to support multiple specifications?

Use a control flow enum, like https://doc.rust-lang.org/stable/std/ops/enum.ControlFlow.html, but perhaps with more variants:

• Ok / Continue (())
• Err / Halt ("")
• Break / Exit (in case the interpreter wants to exit? Probably works fine as a halt like it is now)
• Interrupt / Pause / Breakpoint / Step
• Wait / VBlank
