ETA（ ESTIMATED ARRIVAL） 预计到达
-
在pip中也有eta
计算公式 (v 为速度， sp 为当前进度，st 为总进度，t 为时间):
v = s p t v=\frac {s_p} {t} v=tsp??
p e r c e n t = s p s t ? 100 % percent = \frac {s_p} {s_t} · 100\% percent=st?sp???100%
e t a = s t ? s p v eta=\frac {s_t - s_p} {v} eta=vst??sp??
eta转换为00:00:00的形式，当速度为0和完成时，记为--:--:--
