Test example is broken

[dev590t]

Describe the bug Empyrial/test/rebalance_test.py and Empyrial/test/optimizer_test.py doesn't run.

To Reproduce

(base) pdm run python Empyrial/test/rebalance_test.py 
Traceback (most recent call last):
  File "Empyrial/test/rebalance_test.py", line 14, in <module>
    empyrial(portfolio, rebalance = True)
TypeError: empyrial() got an unexpected keyword argument 'rebalance'
(base) pdm run python Empyrial/test/optimizer_test.py 
Traceback (most recent call last):
  File "Empyrial/test/optimizer_test.py", line 9, in <module>
    optimizer(portfolio, "EF")
NameError: name 'optimizer' is not defined

I can't find the function optimizer in the code, and the parameter rebalance in the header of function empyrial

Hello,

Yes, the optimizer function has been removed.

Here is the doc where you will see how to optimize and rebalance your portfolio now: https://empyrial.gitbook.io/empyrial/

Hope it helps!
