More fine grain control on what Date columns use .timestamp vs .date, etc...

Improve DateEncodingFormat Support

There is only one way per table to set all columns using Date to one format. For example:

public static var dateEncodingFormat: DateEncodingFormat = .timestamp

or

public static var dateEncodingFormat: DateEncodingFormat = .date

Steps to Reproduce

public fileprivate(set) var date: Date
public fileprivate(set) var updated: Date

public static var dateEncodingFormat: DateEncodingFormat = .timestamp

In this example, var date: should be .date, and var updated: should be .timestamp, to be more fine grained to their respective use cases in this table.

Expected vs. Actual Behaviour

• [ ] Expect each column to be able to independently handle date format style.
• [ ] Actually happening, each column takes the one format.
