[needs help] feature request - export with json

[rozxter1]

Currently -export makes two files .ies .bss.

There could be also -exportjson

In result it would generate .ies .bss + .json file, containing formated extracted data like its in "--json" output, but it would be stored for each MAC address next to .ies .bss files

I think the approach I'd accept in a PR would be to also export a .json file alongside the .ies and .bss file when using the -export option. I'm not interested in maintaining and supporting an additional CLI option for this.
