`RegisterSymmetric` allows a downstream user to add their own desired AEAD to the symmetric package.
## Implementation strategy
The golang implementation of what is proposed is rather straight forward.
The concern is that we will break existing private keys if we just switch to this.
If this is concerning, we can make a simple script which doesn't require decoding privkeys,
for converting from the old format to the new one.
## Status
Proposed.

* Allows downstream users to add their own AEAD
### Negative
* We will have to break all private keys stored on disk.
They can be recovered using seed words, and upgrade scripts are simple.
### Neutral
* Caller has to instantiate the AEAD with the private key.
