implement truncated exponential backoff with jitter

[adk-swisstopo]

The -d option supports multiple delays but if a user wants to implement (jittered) exponential backoff they still need to do the calculation themselves. Could you please add an option that generates a reasonable backoff sequence directly?
Even better if we can have a jitter option, that can be separate.
