No way to test strings nicely

[cooldome]

ut:expect(a == "asba") doesn't produce nice error message, no suffix to create ut::TExpr for strings

Suggestion:

introduce suffix for strings, but "_s" is already taken, so it can be either "_str" or "_sv" for string_view.

ut:expect(a == "asba"_str)
ut:expect(a == "asba"_sv)

Would you mind explaining how you got it to work? :)
