Narrow unicode builds for Python 2.7

[henryiii]

On PyPI, narrow-unicode wheels are not provided. This causes my Azure pipelines that uses Pandas to take 8 minutes on the Python 2.7 versions instead of 45 seconds for all other Python 3 versions. The manylinux container does have both "cp27mu" and "cp27m" versions - and Azure is using the narrow-unicode one. Numpy does provide this narrow-unicode wheel, so it's only Pandas doing the build.

Could narrow unicode builds be provided as well on the current 0.24 or the next patch release to it? It would be a file like *cp27-cp27m-manylinux1_x86_64.whl in addition to cp27-cp27mu-manylinux1_x86_64.whl .

we are no longer supporting 2.7, so this request is unlikely
