Gcalcli

* Drop support for python <3.10
* Add `init` command to explicitly request auth setup/refresh
* Improve auth issue handling and error messaging or invalid OAuth token
issues (adrien-n)
* Respect locally-installed certificates (ajkessel)
* Re-add a `--noauth_local_server` to provide instructions for authenticating
from a remote system using port forwarding
* Add support for config.toml file and `gcalcli config edit` command
* Behavior change: `--noincluderc` now skips gcalclirc files unconditionally,
w/ or w/o --config-folder
- POSSIBLE ACTION REQUIRED: Use `path/to/gcalclirc` explicitly if it stops
reading an rc file you needed
* Migrate data files like ~/.gcalcli_oauth into standard data file paths
(with fallback to migrate detected files into the new paths)
* Add support for $GCALCLI_CONFIG env var and deprecate --config-folder
* Add support for `gcalcli util config-schema|reset-cache|inspect-auth`
commands
* Fix parsing for calendar names containing ''
* `add` and similar commands determine date format to use based on system
locale's in "When" inputs
* `add` with `--default-reminders` won't prompt for additional reminders
* Fix `import` crashing on empty ICS files
* `import` can also handle events w/o a dtend, using duration if available
* The `import` command now dumps events it couldn't import into a tmp rej.ics
file in a tmp directory for convenient retries

* Fix lots of bugs by switching from deprecated oauth2client to
google_auth_oauthlib
* Friendlier help output when `import` command is missing vobject extra
* `import` command more gracefully handles existing events to avoid duplicates
and unnecessary edits (tsheinen, cryhot)
* Handle encoding/decoding errors more gracefully by replacing with
placeholder chars instead of blowing up
* Fix `--lineart` option failing with unicode errors
* `quick` command now prompts for which calendar to use when ambiguous
* Fix `--nodeclined` option failing on events with aliased email
* Fix event list commands like `agenda` returning some events that don't
actually match their search criteria due to pagination bug (kbulygin)
* `add` command now supports `--end` as an alternative to `--duration`
