Write meter readings to AEMO NEM12 (interval metering data) and NEM13 (accumulated metering data) data files


# Accumulated Data (NEM13)

```python
from nemwriter import NEM13

m = NEM13(to_participant='123')
ch = m.add_reading(nmi='123',
nmi_configuration='E1B1B2',
register_id='1',
nmi_suffix='E1',
previous_read=412,
previous_read_date=datetime.datetime(2017,1,1),
previous_quality_method='A',
current_read=512,
current_read_date=datetime.datetime(2017,2,1),
current_quality_method='A',
quantity=100,
uom='kWh'
)
output = m.nem_output(file_name='output.csv')
```

Will output:
```
100,NEM13,201701010101,,123
250,123,E1B1B2,1,E1,,,E,412,201701010000,A,,,512,201702010000,A,,,100,kWh,,,
900
```

# Interval Data (NEM12)

```python
from nemwriter import NEM12

m = NEM12(to_participant='123')
readings = [
# read end, read value, quality method, event
[datetime.datetime(2004, 4, 18, 0, 30), 10.1, 'A', 'Power Outage Alarm'],
[datetime.datetime(2004, 4, 18, 1, 0), 11.2, 'A'],
[datetime.datetime(2004, 4, 18, 1, 30), 12.3, 'A'],
[datetime.datetime(2004, 4, 18, 2, 0), 13.4, 'A'],
]

ch = m.add_readings(nmi='123',
nmi_configuration='E1B1B2',
nmi_suffix='E1', uom='kWh',
interval_length=30,
readings=readings)
output = m.nem_output(file_name='output.csv')
```

Will output:
```
100,NEM12,201701010101,,123
200,123,E1B1B2,,E1,,,kWh,30,
300,20040418,10.1,11.2,12.3,13.4,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,V,,,,
