Exchangelib

-----

-----

- Make `FileAttachment.fp` a proper `BytesIO` implementation
- Add missing `CalendarItem.recurrence_id` field
- Add `SingleFolderQuerySet.resolve()` to aid accessing a folder shared by a different account:

python
from exchangelib import Account
from exchangelib.folders import Calendar, SingleFolderQuerySet
from exchangelib.properties import DistinguishedFolderId, Mailbox

account = Account(primary_smtp_address="some_userexample.com", ...)
shared_calendar = SingleFolderQuerySet(
account=account,
folder=DistinguishedFolderId(
id=Calendar.DISTINGUISHED_FOLDER_ID,
mailbox=Mailbox(email_address="other_userexample.com"),
),
).resolve()
