Add file encryption in addition to string encryption to the integration

Currently, the integration works if you're trying to encrypt a strong and store it on ceramic and gate it using Lit.

Could we add the relevant functions that also encrypt a file and then store the encrypted file contents on ceramic?

I think you can do this by base64 encoding the file (to turn it into a string)
