Milliseconds support

[qb-0]

import schedules, times, os

schedules:
  every(milliseconds=20, id="tick", throttle=30):
    echo("tick ", now())
    sleep(5000)

Fails currently with [DivByZeroDefect]

My bad. Param seconds is still required. Works fine.

import schedules, times, os

schedules:
  every(seconds=0, milliseconds=5, id="tick", throttle=30):
    echo("tick ", now())
    sleep(5000)

Seems that it randomly compiles and randomly fails with DivByZeroDefect

@qb-0 Currently, nim-schedules uses Second as the minimal resolution (fromUnix). I guess we can update the library by using fromUnixFloat, which supports subsecond as resolution.

In my experience, the smallest possible interval is 2 seconds. Anything below that will still result in an interval of "every 2 seconds".
