Feature request: auto bake interval

**Is your feature request related to a problem? Please describe.**
If you use e.g. the "Generate TOTP" it would be great to be able to automatically bake every X seconds.

**Describe the solution you'd like**
First idea would be an option to set the interval next to "Auto Bake". Something like "0" = never and everything else is interval.
Also it would be great to have it in the URL so that it can be shared.

**Describe alternatives you've considered**
As it only make sense for some operations like "Generate TOTP" or "Generate HOTP" it could also be included into those operations.
