Added an option to set the target decryption time on database creation
for the CLI create command. This required some refactoring, in
particular the extraction of the min, max and defaut decryption times in
the `Kdf` module. Some work was done to allow changing those constant
only in the `Kdf` module, should we ever want to change them.
The CLI now contains an "import" command that creates a new database from the specified XML export. The new database is in kdbx 4 format, and does not currently accept a keyfile in database creation.
This change is required to create new databases from XML backups.
Fixes#2458
* Empty destructors are replaced with default destructors
* A few loop variables made into const references to avoid copies
* Add missing `override` spec for some `Command::execute` methods
