nixd: emove nix ANSI color but not add unit test (#14)
8dcde63 
`ASSERT_TRUE(SRO.contains(R"("whatEverUndefined)"));` can not pass not
because ansi but the redundant `"`, so I remove the comment.

the reason why I not add unit test is that I can not find ANSI code in
the output of `SRO.str()` and `Diagnostics[0].message`

Fixes: #10

libnixf: fix out-of-bounds access in Lexer::consumeManyOf (#443)
9ab3f1f 
While bumping my system flake I ran into a test failing due to an
out-of-bounds access. It got caught by `_GLIBCXX_ASSERTIONS`. I guess
the not-so-recent
[bump](https://www.github.com/NixOS/nixpkgs/pull/298047) of meson in
nixpkgs brought in this
[commit](https://www.github.com/mesonbuild/meson/pull/12683) from meson
1.4.0.

Here's the failing test logs and a backtrace:

```

Maybe it's a good idea to bump nixpkgs for the new default meson
behavior
or enable stdlib assertions with bounds-checking explicitly?
