Capture ratio support annualization?

[huaiweicheng]

Here is my scenario.
I have returns, which is measured by quarter.
Then I wanna to calculate the up and down capture ratios using empyrical.
However, I find the capture function in stats.py does not support annualization.

Thus, I cannot make the calculation.
Simply Adding the annualization param will be fine since the annual function support the annualization param.
