Annotated CSV support ?

Hi...
[Any plans on supporting Annotated CSV ?](https://v2.docs.influxdata.com/v2.0/reference/syntax/annotated-csv/extended/)

Something like this :
```csv
m|measurement,location|tag|Hong Kong,temp|double,pm|long|0,time|dateTime:RFC3339
weather,San Francisco,51.9,38,2020-01-01T00:00:00Z
weather,New York,18.2,,2020-01-01T00:00:00Z
weather,,53.6,171,2020-01-01T00:00:00Z
```
