(Partial) Support for no_std #20
Description
It would be really nice to be able to use this crate or a subset of it in no_std environments.
Most parts currently imported from std:: have equivalents in core::.
After a quick look, the biggest show stopper is the missing of an Error alternative in no_std environments.
Maybe parts of the crate can be left out but it would be really cool to use humantime in IoT projects.
