Closes #15445 from jreback/windows and squashes the following commits:

a5b7fb3 [Jeff Reback] change integer to power comparisions
eab15c4 [Jeff Reback] don't force remove pandas
cf3b9bd [Jeff Reback] more windows fixing
efe6a76 [Jeff Reback] add cython to build
8194e63 [Jeff Reback] don't use appveyor recipe, just build inplace
e064825 [Jeff Reback] TST: resample dtype issue xref #15418
10d9b26 [Jeff Reback] TST: run windows tests so failures show up in appeveyor
