Support different sorts of type annotations

PR #50 adds support for type annotations with sorts `FIELD`, `METHOD_RETURN` and `METHOD_FORMAL_PARAMETER` (See `org.objectweb.asm.TypeReference.getSort`)

However the following sorts could also be supported:

* `CLASS_TYPE_PARAMETER`
* `METHOD_TYPE_PARAMETER`
* `CLASS_TYPE_PARAMETER_BOUND`
* `METHOD_TYPE_PARAMETER_BOUND`
* `THROWS`
* maybe some other sorts
