Change subject: [bugfix] load siteinfo from API if expiry=True in
Siteinfo.get() method
......................................................................
[bugfix] load siteinfo from API if expiry=True in Siteinfo.get() method
- Siteinfo._is_expired(): follow boolean expire value
- Siteinfo.get(): test for not isinstance(expiry, (bool, timedelta))
because a boolean variable is an instance of int too
- Siteinfo.get(): do not load siteinfof from cache if expiry is True
- assign force to Siteinfo.get() in __call__ method
- use expiry=True instead of expiry=0
- fix result in Site.live_version method according to the doc typing hint
- simplify some code
- add some type hints
