… on ARM64

this command

MethylDackel extract --methylKit -q 20 --CHH --CHG --nOT 0,0,0,4 --nOB 0,0,5,0 reference.fa arm_missed_call.bam

produces this error message:

Invalid bounds string, 0,0,0,4
Invalid bounds string, 0,0,5,0

which proceeds, ignoring the bounds strings.

@dpryan79 i think the errors in CI are unrelated... something about miniconda
