Unable to convert bed to States Data (multivec) file using clodius bedfile-to-multivec

Hi Developers,

I am trying to convert a bed file to States Data (multivec) file, ingest the multivec file to my higlass server and try to display the tracks on the website. However, the multivec, the output of `clodius bed_to_multivec,` cannot be loaded correctly on my Higlass website.

I was using the example [bed file](https://github.com/higlass/clodius/raw/develop/test/sample_data/states_format_input_testfile.bed.gz) and [row info file](https://github.com/higlass/clodius/raw/develop/test/sample_data/states_format_test_row_infos.txt) as the input of `clodius bed_to_multivec` and trying to get the example [output](https://github.com/higlass/clodius/raw/develop/test/sample_data/states_format_output_test_file.multires.mv5) using the following command:
`clodius convert bedfile-to-multivec states_format_input_testfile.bed.gz \
--format states \
--row-infos-filename states_format_test_row_infos.txt \
--assembly mm9 \
--starting-resolution 200 \
--num-rows 10`
I used `diff` to check if my output `states_format_input_testfile.bed.multires.mv5` differs from the [example output](https://github.com/higlass/clodius/raw/develop/test/sample_data/states_format_output_test_file.multires.mv5) and they are different. And after I ingested my output to my Hilglass webpage, it keeps loading and cannot display the track.

Can you check what is the reason. I used `pip3 install clodius` to install and the convert command of my clodius is `bedfile-to-multivec` instead of what the tutorial command `bedfile_to_multivec`. Is my issue due to the clodius version difference? Thank you very much.

Best,
Haoting
