Unit test failure on Mac arm64

[hpages]

Similar to knncolle/BiocNeighbors#21, LTLA/csaw#21, and LTLA/metapod#1.

See details of the failure on the Mac arm64 semiweekly report: https://bioconductor.org/checkResults/3.18/bioc-mac-arm64-LATEST/batchelor/kjohnson1-checksrc.html

As a consequence, there's no Mac arm64 binary in BioC 3.18: https://bioconductor.org/packages/3.18/batchelor

Thanks,

Looks like an actual error but I can't diagnose it without my work laptop, so just skipped the test for the time being.
