format_weather() fills empty times the errors when NA values detected

[PaulMelloy]

format_weather() automatically will fill any missing times. when filling time gaps it will fill the temperatures, rain and wind as NA.
Then it checks the data and errors because there are NA values.

The following needs to be implemented for informed troubleshooting

1. Error messages need to specify the possibility of missing data
2. Use the impute functions to automatically fill data on request
3. Warning message to user so they know when data is missing

[PaulMelloy]

format weather should only format in UTC to ensure daylight savings does not introduce errors. Currently this is done to an extent, however perhaps more tests need to be made to ensure it is done adequatley
