Add use of pendulum for date/datetime management

Is your feature request related to a problem? Please describe. I recently found pendulum and started using it as my default date and datetime management library since the standard python datetime module is not very rich.

Describe the solution you’d like It would be nice if we could choose either to use the standard datetime module or to use pendulum as our default library to type date/datetime properties.

I’m already using pendulum types in pydantic models I coded manually and so far so good! These types are pendulum.Date and pendulum.DateTime and pendulum.Time.

@dreinon I’m sorry for my late reply. It’s interesting. I will add the task to a TODO list. Thank you!!

In order to make Arrow pydantic-compatible, the following page from the pydantic docs can be followed, that says that any class can be made pydantic compatible by setting a couple methods for validation and schema generation

@dreinon I think it won’t be enough. What is needed is discussed in this issue: https://github.com/samuelcolvin/pydantic/issues/951

Pydantic just doesn’t have all needed features yet, although various workarounds are possible.
