Add method to check if storage file already exists #88

Hello

I use biometric storage to store a secret (generated EC key pair) at the first launch of my app. I have to check if the secret was already generated on subsequent launches without showing the authentication prompt if the secret already exists.

Can you add a method to storageFile which checks if the file already exists?
