Make it possible to check that an implementation is supported at runtime (#1197)

Browse Source 
* Make it possible to check that an implementation is supported at runtime.

* add CI fuzzing on arm 64 bit

This adds fuzzing on drone.io arm64

For some reason, leak detection had to be disabled. If it is enabled, the fuzzer falsely reports a crash at the end of fuzzing.

Closes: #1188

* Guarding the implementation accesses.

* Better doc.

* Updating cxxopts.

* Better doc.

* Updating cxxopts.

* We need to accomodate cxxopts
