CheckScimError cannot be determined when wrapped #185
Description
If you wrap ScimError with fmt.Error() or similar, it will not be recognized as a ScimError by CheckScimError.
To make it easier to handle errors, I would like to judge them using errors.As() rather than err.(ScimError).
Would you be so kind as to accept the PR to replace errors.As?
I'm happy to work on this if it's likely to be accepted.
