`Vec<Vec<u8>>` conversion support missing

[jq-rs]

Hello! Thanks for this great crate! I tried to add Vec<Vec<u8>> under efficient bytes conversion but was unable to. Probably expected, would it be possible to add such support?

More detailed errors below:

I was able to workaround this with a separate struct definition. Closing.
