I think this task really needs some researches on how to properly measure objects separately

[the2pizza]

depends on brurucy/indexset#35.

@the2pizza You need to make macro usable with enums too. Last error is in tests, because it panics on SomeEnum deriving.

[the2pizza]

@Handy-caT A bit reworked, added more primitives and macro for them, test've been fixed

Question - should we support chrono crate time types? I suppose it's usable for end users, we can add cfg option for chrono as well

[Handy-caT]

@the2pizza You can add it in separate PR
