Allow missing arrivalDate attrs

The earliestEstimatedArrivalDate and latestEstimatedArrivalDate attributes have mysteriously vanished from the API v3 docs. And their absence is causing an error

This fixes issue #18

We also bump some dependancies up to stay updated with security releases.

Handle packingSlipUrl updates

As highlighted in #14 and tbuehlmann/dry-struct-setters#2 the use of optional key attributes? :packingSlipUrl creates an invalid setter packingSlipUrl?=

While waiting for an update to dry-struct-setters, this version allows for the packingSlipUrl attribute to be updated.

Properly handle image exceptions

• Logs errors when attempting to add invalid images
• Adds .env use to manage development env variables
• Updates dependancies to avoid some security vulnerabilities

Properly handle packingSlipURl

There is an omitable key packingSlipUrl in the order attributes, we can now accept that data.

Fix issue with partial Pwinty::Image.attributes hash

See #3 and #4 for the issue and the fix.

In short, sometimes the Pwinty API returns image data with attributes: nil, sometimes with attributes: {} and sometimes with attributes: {key: value} and we need to be able to handle all of those cases.

We accomplish this with https://dry-rb.org/gems/dry-struct/1.0/recipes/#tolerance-to-missing-keys

Correct list API use

The API docs describe the use of count and offset as params to pass to the list endpoint while paging through the order list.

This is a mistake in the API docs. Now, the gem uses the correct limit and start params.

The Pwinty::Order.list can also take a page_size attribute which will set the size of each page while looping through them. I've defaulted to 50 as this was the fastest way to get 500 orders in the very limited speed testing I performed.
