f4de00d8b5 examples: boids: use std.log.info instead of std.debug.print 
std.debug.print uses IO which depends on file system and thus needs
support from OS, which dont have in freestanding targets (like WASM).

3bb45c75a1 mach: introduce cross platform Timer abstraction 
This Timer uses std.time.Timer as backing timer in native platforms, and
will use custom timers for special platforms (wasm, android?, ios?).

Unlike std.time.Timer, its primary API is focused on floats. Also meant
to provides some convenient functions alongside base ones.

Follows std.time.Timer API, but methods by default return f32 i.e
non-precise variant with precise variants available returning u64.
