CreateAVR: Refactor ATmega328p

[atluft]

I would like to refactor the existing ATmega328p implementation to utilize the implementation mentioned in pull request 138: Add ATmega32

Definition of done:

1. Refactor the existing ATmega328p chip details in a single file named src/chips/ATmega328p.ts
2. Implement the CreateAVR function as provided in the ATMega32 effort
3. npm test reports all tests passed
4. npm start demo shows a blinking led

My ultimate goal is to add the ATtiny841 and believe this is a solid step towards adding any new chip, ATtiny841, ATmega32, and so on.

Here is a GIST for ADC testing. Created this section to convey one possible approach. Open to other ideas.

import { ATmega328p } from '../chips/ATmega328p';
import { createAVR } from '../create-avr';

. . . SNIP . . .

    const avr = createAVR(ATmega328p, { program: program });
    const cpu = avr.cpu;
    const adc = avr.adc;
    const runner = new TestProgramRunner(cpu);

Notice:

• createAVR is being utilized
• New / refactored ATmega328p configuration is provided as input argument
• program remains unchanged from existing
• cpu and adc are instantiated by createAVR using the ATmega328p configuration
• in the future new Chip configurations could be utilized and tested as needed
