refactor: less #[inline(always)]

[FreezyLemon]

It's a bit unnecessary to have inline(always) on getter functions IMHO. The polyX functions are also very small, so a normal inline attribute is enough.

Could you change the ones you removed to be normal #[inline] instead? I think the original intent of these was to allow them to be inlined across crates, since they're so small and Rust does not do that by default unless you enable LTO. I can't remember the reasoning for setting them to #[inline(always)], but it does indeed seem unnecessary.

[FreezyLemon]

Sure. I didn't actually know Rust inlined across crates at all without LTO, it's good to know that #[inline] enables that

Thanks!
