Implicit dependency on rust compiler

[jeffsf]

It appears that the change to orjson created an install-build dependency on having a rust compiler. As this is unusual for smaller or secured systems, I'd suggest at least notes in the README.

In most cases the Rust compiler is not required. You need it because you're running FreeBSD and orjson doesn't publish FreeBSD wheels. https://pypi.org/project/orjson/#files

Thanks for looking into it.
