Crates.io version of linfa_kernel fails to compile.

[ArvidHammarlund]

Is there anyone else who received similar error while trying to compile the crates.io version of Linfa_kernel? The problem doesn't exist while using the git cloned version of the crate. I'm using a Macbook M1, and if the problem exists for others it might be a good idea to do a new release? Either way, it seems that the SPRS feature is the cause of the problem.

This happens for me, too. One solution is to specify sprs = "=0.11.0" in your dependencies. See also sparsemat/sprs#330 and #307.
