1.2.1

• For this and subsequent releases, third-party libraries will not be included in the release, since we want to avoid these dependencies taking up space in the git repository.
• Added the get_key() method to fetch information about a license key without performing an activation.
• Add a new way to compute machine codes based on information from Systemd, DBus as well as the file system.
• Support changing the library type in CMake by setting the CRYPTOLENS_LIBRARY_TYPE cache entry in CMake.
• Fixed a bug in the deactivate() method which caused problems when deactivating floating licenses.
• Fixed constants belonging to the ActivateError class that were out of sync with the rest of the library.
