Re-distributing auto-round

Hi,

I'm a maintainer at conda-forge package distribution channel and would like to re-distribute auto-round.
I see that the license is Apache-2.0 for the code. However, there are pre-compiled binaries like
`alg_ext.abi3.so`, and there is no information about how to compile it from source nor whether they are
re-distributable as binaries. Can someone clarify?
