Alternative time/memory units in config

[tonowak]

Currently it's possible to specify the time limit and memory limit in ms and kb, but one could make a mistake in the three zeros. It's also a bit not readable -- it takes a bit of time to understand that 16000ms is 16s and not e.g. 1.6s.

What I propose:

• leave the possibility of specifying in ms and kB,
• add a new way to specify time and memory: memory_limit_mb and time_limit_s, which takes consecutively an integer and a float,
• implement the same in sio2,
• assert that when someone specifies e.g. both memory_limit and memory_limit_mb, then their values are equal (e.g. 1000 and 1).

What do you think @MasloMaslane ?

[tonowak]

That would also solve the issue that some people specify the memory limit in powers of 1000, and some in powers of 1024.

(I'm still not sure which one is correct in sio2.)

I think that's a good idea, but first I'd like to split sinol package management away from sio2 and sioworkers code. I'll try doing that in the coming months
