added ${Name} as variable for save path (CLI only)

I'm using blobsaver with a lot of different devices (awesome project BTW :). The saved blobs can currently only be uniquely identified by the ECID, Generator or APNonce, none of which are easy to remember when working with multiple different devices. IMO it would be easier to save the blobs into a subdirectory with a name one can specify, i.e. the "saved device" name.

With the current changes this only works in CLI mode for imported/saved devices when requesting in background (my use-case).

However if you want I can add further changes to make it possible in the GUI as well:
I propose a new "Name" field in the GUI, possibly above the ECID field. This would make the "Name Device" popup obsolete (at least when a name is already given). Then when building the TSS object the Name would be accessible in Controller.java:656 (createTSS).

While I'm at it: In https://github.com/airsquared/blobsaver/wiki/Building you define JDK 19 however build.gradle and the github actions seem to already use JDK 20. Just fyi :)

This looks good, thanks for the contribution!

I don't know about making a new name field available (already too many configuration options in the UI), but maybe when a saved device is selected in the GUI, the saved device's could be used.

Fixed :)

Alright, I had a look and somehow thought it would be more complex. I needed to add a deviceName variable in Controller since selecting a device is handled in a callback and after focus loss the device is deselected from the deviceList (i.e. it is currently not persisted upon selection).

I also added a warning if the user uses ${Name} without first selecting a saved device.

Any thoughts?

Looks good, merging
