`topola-gear-sectors` has license `MIT OR Apache-2.0`,
because it copies large amounts of code directly from
rusts `alloc` standard library.
It implements something like an associative map from
angles to arbitrary values, but also supports inspecting
the intervals between angles in the map.
I ran the following command in Fish shell:
```
reuse annotate --skip-unrecognised --copyright="Topola contributors" --license="MIT" **.{rs,md,toml}
```
The choice of year 2024 in the copyright statements is intentional.
