SubGhz: File naming fixes and improvements

[geckom]

Description of the feature you're suggesting.

Currently when you save a SubGhz file with a timestamp filename you get something like this "SubGHz_2024-01-12_09,43.sub"

Since the resolution is only down to the minute, if you try to save 2 captured within the same minute you will need to rename the second file to something different.

Proposed solution - add a seconds number to the file name ie. SubGHz_2024-01-12_09,43,42.sub

Anything else?

Hi, I also encountered this problem when I had the "Bin RAW" function of the Sub-GHZ turned on. I'm not using this at the moment, but switching it in "Settings - System - File Naming - Random" might help. Try it

addressed this in 461026e, it now includes seconds too.

also, i noticed that subghz used the time of you pressing "save" for the timestamp. added a new api in 7e7509d to generate filenames with custom timestamp, and fixed subghz to use it in a1c7dc5. now subghz uses timestamp of signal receival.

also, with 411a65a you can choose to have timestamps before the protocol name, which can be useful for sorting.
