add nicehash support

[wong-fi-hung]

added nicehash support (reduce reject rate when using nicehash stratum).
added --nicehash option.
fixed hashrate calculation(util.cpp) : hashrate < 1000 = H/s
hashrate < 1e6 = KH/s
hashrate < 1e9 = MH/s
hashrate < 1e12 = GH/s
hashrate = 1e12 = TH/s

It will be helpful if you could add static linking for the build
May be a separate build considering final executable might have larger file size

@wong-fi-hung can you document down how to do the static linking ?
When I try one fails when the other works
Can't find the right way
