Adding a function for returning a list of API calls made by date:
```py
> san.api_calls_made()
[
('2021-11-19T00:00:00Z', 1),
('2021-11-22T00:00:00Z', 2),
('2021-11-23T00:00:00Z', 3)
]
```
...
and a function to return a dict of remaining API calls:
```py
> san.api_calls_remaining()
{
'month_remaining': '1000',
'hour_remaining': '500',
'minute_remaining': '100'
}
```
