Describe the bug
Dear author:
When using the example data provided by plotsr for operation, the following error was reported:
"ValueError: mz is not a valid tag".
The operation command was: "plotsr --sr col_lersyri.filtered.out --sr ler_cvisyri.filtered.out --sr cvi_erisyri.filtered.out --genomes genomes.txt --tracks tracks.txt --markers markers.bed --cfg base.cfg -o output_plot.png -S 0.5 -W 7 -H 10 -f 8".
I am using python=3.8.20, plotsr=1.0.3
