ErrBitStateNotFound error is missing

[yaronius]

Hi! I come from an older version of this library which was github.com/snowman-mh/device-check-go and it is redirecting me to this repo now. And I see that the older version was using ErrBitStateNotFound which is missing in this repository. The only trace of this error is found in README and is kind of misleading because the SDK doesn't return this error now:

if err := client.QueryTwoBits("DEVICE_TOKEN_FROM_CLIENT", &result); err != nil {
	// error handling
	// Note that SDK returns ErrBitStateNotFound error if no bits found
}

What would be a suitable replacement for this error in the current version of SDK? I browsed the code and didn't find any. It would be nice to update the README as well.

Thank you for filing a bug!

This issue was fixed by #12 (thanks to @peter-meemo) and some more tests were added by #13 .
And I released a new version https://github.com/rinchsan/device-check-go/releases/tag/v1.2.0 including above bug fixes.

Feel free to re-open this or open a new one if you find any degradations.
