Subject: [PATCH] base: Add `maybe_unused` to `findLsbSetFallback`

When compiling with clang-14 I received the following error:

```
src/base/bitfield.hh:328:1: error: function 'findLsbSetFallback' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]
```

This function was introduced in PR #76.
This fixes this compiler warning/error by using `[[maybe_unused]]`.
