[0.17] Increase belt speed for consistency

TL;DR
Belt speeds should be 16/s, 32/s and 48/s

What ?
I'm suggesting that you should increase belt speeds to make numbers clean.
Why ?
With the 0.17 changes belts have 8 items on them on each tick. Since the new belt speeds (15/s, 30/s, 45/s) are not multiplies of 2, this causes inconsistent troughput per second.
For example: When you count full blue belts' items with pulses, you get 44 or 46 for each second.

Increasing the speeds to 16/s, 32/s and 48/s will solve this problem and makes calculations cleaner.
Also smelting time of the plates should reduce to 3 seconds to keep the 48 furnace ratio.

Belt speeds / item spacing were already changed in 0.17 to specifically address this issue !

1 pixel / tick x 60 ticks / second x 1 tile / 32 pixels x 8 pixels / item = 15 tiles x pixels / second / item
Ok, I'm not sure why I don't end up with items / second, but this seems to be the actual calculation...
15-30-45 seem to be the cleanest numbers you can have under these conditions.

That issue with blue belts might be something different ?

I wonder if this is related ?

1 pixel / tick x 60 ticks / second x 1 item / 8 pixel = 7.5 item / second on 1 lane.

Duh, of course - I don't know how I managed to forget about the two lanes, I use single lanes extensively in my designs ! - and if the size of the tile doesn't matter for the end speed, neither does it for the intermediate calculation ! Thanks !
