Improve b2s or replace with custom code (unneded wide strings support)

[mr-tz]

binary2strings reads utf8 and wide strings (we don't expect or require the latter for Rust strings extraction).

In rust-hello64.exe we see

Which parsed as wide string starting at offset 0x1400BD04F, b2s sees as:

We then filter out the wide string and end up with args in the final Rust strings output.

Bumping the min_string length to 6 also mitigates this, but we could then miss shorter strings.

So, should we work on implementing something similar to b2s using Python?

Yes, currently we only require a function to find UTF-8 strings though.
