## parse_datetime_to_timestamp
```python
parse_datetime_to_timestamp(data)
```

Input a date-time text string of several formats and convert to a naive or timezone-aware epoch timestamp in UTC

Parameters:

    data:        (string) a string representation of a date-time in several supported formats

Returns:

    Dict/None    A Dictionary of the following format:

                 {
                     "format":               integer,     # for debugging purposes
                     "timestamp_naive":      integer,     # timestamp based on locally configured timezone
                     "timestamp_utc":        integer      # aware timestamp only if UTC timezone detected
                 }

                 The format integer denotes which date_time format conversion succeeded.
                 The timestamp_naive integer is the converted date-time string to a naive epoch timestamp.
                 The timestamp_utc integer is the converted date-time string to an aware epoch timestamp
                     in the UTC timezone. If an aware conversion cannot be performed (e.g. the UTC timezone
                     is not found in the date-time string), then this field will be None.

                 If the conversion completely fails, None is returned instead of a Dictionary
