Improve language-strings storage (JSON) and show value to users

[mr-tz]

Currently, the result document JSON contains:

1. static_strings: all static strings
2. language_strings: language-specific strings
3. language_strings_missed: all static strings minus what was found in 2.

This results in:

• a bunch of duplicate data
• false/confusing entries in 3., e.g., it currently includes all strings found outside the targeted language-specific sections like .data or .rdata

We also don't show the real value clearly yet. Like with FLOSS we see x more strings now easily digestible by humans.

Solution ideas:

1. remove language_strings and language_strings_missed and just update static_strings - easiest
2. don't include static strings for language samples
3. ...

until we guarantee the format of the JSON output, we may want to consider using keys like language_strings_UNSTABLE so that people know not to rely on them yet.

My current ideas:

• leave 1. and 2. but update 3. language_strings_missed to only include language strings that FLOSS should have extracted but didn't
• render language strings separately from static strings

Language strings are part of static strings and it's currently not possible to display them separately. This can be added later, if desired.
