Nanoseconds ignored when writing Points with RFC string format

See: influxdata/influxdb-python#829 (comment)

I believe this library suffers the same problem.

influxdb-client-python/influxdb_client/client/date_utils.py

Line 10 in 8c167e9

As you mentioned the datetime has a precision to microseconds and also almost all time libraries are without supports of nanoseconds:

• pendelum
• udatetime
• isodate
• arrow

We will have to use something like pandas timestamp:

>>> import pandas as pd
>>> pd.to_datetime('1996-02-25T21:20:00.001001231Z', unit='ns')
Timestamp('1996-02-25 21:20:00.001001231+0000', tz='UTC')

Hi @fcoetzee,

we preparing workaround by pandas.Timestamp.

For detail info see #141 or this example nanosecond_precision.py.
