Macrobond-data-api

* Fix for get_data_package_list_iterative
* Add get_data_package_list_chunked

- New APIs for in house series

Breaking change

* COM API: Metadata values for attributes that can have multiple values are now always a List.

Example:
py
from macrobond_data_api.com import ComClient

with ComClient() as api:
print(api.get_one_series("usgdp").metadata["Region"])

In 1.0.8 (old behavior) this code would print `'us'`.
In the new behavior in 2.0.0 it will print `['us']`.

* Upgrade dependencies

* Fix for parse_date

* Fix for "4.1 - Macrobond Data API - Revision History.ipynb"
* Fix for SubscriptionList last_modified time of set
* Fix for to_pd_data_frame() in GetAllVintageSeriesResult
