Make an example of encrypting a large file with seperate symettric encryption and Lit encryption of the symmetric key

[hannahhoward]

What

1. Encrypt large blob using the examples from the Lit website
2. Define a format for combining and storing the encrpyted cypher key and symettrically encrypted data hash
3. Store the combined blob on storacha and prove you can get it back, decompose the file and decrypt using your ethereum address

After diving deeper into the docs and exploring the Lit code, I saw that they now support larger files. So, there’s no need to encrypt the file with a symmetric key first. The encryptFile method takes care of it by turning the file/blob into an ArrayBuffer before encrypting.
