OCR with digests other than SHA-1 doesn't work

[koerue]

Describe the issue

When scanning an QR code made with the SHA-256 or SHA-512 digest, the App doesn't respond incorrect OTP's. However OCR scanning SHA-1 hashed QR's returns valid OTP's.
You can reproduce the error here:
https://www.token2.com/shop/page/token2-totp-toolset-sha256-version
(offers SHA-1 also)

When adding the (e.g.SHA-256) secret manually to the extension, this issue doesn't appear.

Hi,

I can confirm. Any news on this issue?

Hmmm, because the extension only knows SHA256 but not sha256, I will create a PR later.
