Add method to simplify standardized domain parameters

This can be used to extract simplified AlgorithmIIdentifiers from
existing Key objects. As already done in AbstractCaProtocol and
RiProtocol.

Implementation pending, default fallback to return the provided input
already works ;-)
Add initial StandardizedDomainParametersTest
Add dummy data and testcase that ensures simplify returns unknown
build correct AlgorithmIdentifier structure
Create correct structure for ecdh AlgorithmIdentifier
Encode dynamic instance data in getAlgorithm instead of static dummys
Update JavaDoc
test simplifyAlgorithmIdentifier for all available domain parameters
cleanup code
add values for mapping of standardized domain parameters
fix typo
fixed typos
