* feat(op): user slog for logging
integrate with golang.org/x/exp/slog for logging.
provide a middleware for request scoped logging.
BREAKING CHANGES:
1. OpenIDProvider and sub-interfaces get a Logger()
method to return the configured logger;
2. AuthRequestError now takes the complete Authorizer,
instead of only the encoder. So that it may use its Logger() method.
3. RequestError now takes a Logger as argument.
* use zitadel/logging
* finish op and testing
without middleware for now
* minimum go version 1.19
* update go mod
* log value testing only on go 1.20 or later
* finish the RP and example
* ping logging release
This fixes an issue where, when using the device authorization flow, the
grant type would be set twice. Some OPs don't accept this, and fail when
polling.
With this fix the grant type is only set once, which will make some OPs
happy again.
Fixes#352
* feat: Allow modifying request to device authorization endpoint
This change enables the caller to set URL parameters when calling the
device authorization endpoint.
Fixes#354
* Update device authorization example
