In ValidatorConfig, it's sometimes useful to specify a restriction on SignatureType.
For example, a checker could be specified as:

checker
{
  type hierarchical
  sig-type rsa-sha256
  sig-type ecdsa-sha256
}

The sig-type key should be optional and repeatable.
If sig-type is present, the packet must have any one of the specified SignatureTypes.
If sig-type is absent, the packet may have any SignatureType.

The syntax of sig-type value is to be determined.
It should at least allow specifying the signature algorithm, and could be extended to also specify minimum key length.
