Weekly schedule support

[cristianchelu]

Placeholder issue to keep track of ideas regarding support of different schedules across an entire week, instead of daily.

Aqara Smart Pet Feeder C1 (Zigbee)

• ZHA no support / Z2M supports via mqtt topic publish
• Schedule entry day-of-week encoded as enum:

  const daysLookup = {
   0x7f: 'everyday',
   0x1f: 'workdays',
   0x60: 'weekend',
   0x01: 'mon',
   0x02: 'tue',
   0x04: 'wed',
   0x08: 'thu',
   0x10: 'fri',
   0x20: 'sat',
   0x40: 'sun',
   0x55: 'mon-wed-fri-sun',
   0x2a: 'tue-thu-sat'
  };

Petlibro feeders

• Integration support for schedules discussed in
  [Feature Request]: Control over individual feeding schedules jjjonesjr33/petlibro#26
• Schedule entry encoded as array of day-of-weeks:

  {
      "id": 1270679,
      "executionTime": "04:00",
      "repeatDay": "[7,2,1,3,4,5,6]",
      "enable": true,
      "grainNum": 1,
      /* ... other data ... */
    }
