Add SHA512 hashes

Would it be possible to add SHA512 hashes? I'm looking to mirror a repo that I don't control that only publishes SHA512 hashes in the InRelease file.

@ryanolson should be relatively easy, I'll add that in!

@ryanolson do you have sample of such repo? I would like to add system test

I do, that's my repo:

curl -L https://nvidia.github.io/libnvidia-container/gpgkey | sudo apt-key add -
aptly mirror create -keyring=/etc/apt/trusted.gpg libnvidia-container https://nvidia.github.io/libnvidia-container/ubuntu16.04/amd64 ./
aptly mirror update -keyring=/etc/apt/trusted.gpg libnvidia-container

Fix is available in aptly_1.1.1+45+g9c018ce (nightly build)

Works great!
