/**
* Convert a temporal accessor to a zoned date time object - as performant as possible.
* The .from() methods from the JDK are throwing exceptions when for example ZonedDateTime.from(accessor)
* or Instant.from(accessor). This results in a huge performance penalty and should be prevented
* This method prevents exceptions by querying the accessor for certain capabilities
* and then act on it accordingly
*
* This action assumes that we can reliably fall back to some defaults if not all parts of a
* zoned date time are set
*
* - If a zoned date time is passed, it is returned
* - If no timezone is found, ZoneOffset.UTC is used
* - If we find a time and a date, converting to a ZonedDateTime is straight forward,
* no defaults will be applied
* - If an accessor only containing of seconds and nanos is found (like epoch_millis/second)
* an Instant is created out of that, that becomes a ZonedDateTime with a time zone
* - If no time is given, the start of the day is used
* - If no month of the year is found, the first day of the year is used
* - If an iso based weekyear is found, but not week is specified, the first monday
* of the new year is chosen (reataining BWC to joda time)
* - If an iso based weekyear is found and an iso based weekyear week, the start
* of the day is used
*
* @param accessor The accessor returned from a parser
*
* @return The converted zoned date time
