Add #[inline] to Time::from_hms for performance

[finnbear]

This makes decoding Time in bitcode 6X faster.

It works since bitcode checks the range of integers up front, all at once, using vector instructions, and then uses unreachable_unchecked right before calling Time::from_hms to communicate that fact to rustc. This only works if Time::from_hms is inlinable.

Incidentally I was planning on going through all functions in the coming days and weeks to (re)add #[inline] where appropriate. As such I'll likely end up closing this at that point in time so as to avoid many separate commits for the same thing.

Cool, fine with me! I use from_hms_nano anyway. Closing 👌
