add Macro syntax for argmax and argmin

[mmcky]

This PR adds TeX macros for argmin and argmax which should fix #31

@shlff we should also fix other cases

Would you have time to go through:

and let me know which ones we need?

I would suggest using grep to see if they are needed. For example

grep -r "RR" source/rst/*

will give you a list of all cases of RR

Thanks @mmcky . I checked all cases from \RR to \argmin in the list through all lecture-python lectures via grep and find

• \argmax is the only case we need to fix

Do you want me to check more cases? If not, then I think this PR can be merged safely.
