Source distribution is not available on pypi after 0.6.1

[HiroIshida]

According to https://pypi.org/project/python-fcl/0.0.12/#files, after 0.6.1, no source distribution is released on pypi. This results in failure in pip installing from any ARM machine because wheel distribution is not released in the first place.

Could you release the source distribution when you have time? @mjd3 @mmatl

In fact, On x86 marchine latest version is available
