Bump to 1.4.1a3 (py310)

[roomrys]

Description

This PR skips the attempted previous prerelease of 1.4.1a3 (that does no bumpy the python version). But, we were running into trouble with conflicting h5py packages on the WIndows build manual test. So, here we are - releasing what was intended to be 1.4.1a4 as 1.4.1a3.
