Issue:
Add support for STORM- and VASA-seq
Hi kb_python team - thank you again for all your help getting STORM-seq integrated into ngs-tools and kallisto to run with kb_python. I wanted to open a PR to officially integrate STORM- and VASA-seq into kb_python. Thanks again for a great tool!
requirements.txt says pandas>1.0.0 but breaks on pandas 2
**Describe the issue**
A clear and concise description of what the issue is.

in pandas 2.* the index module has been moved to an upper level (from pandas.core.index to pandas.index) and thus, when installing kb-python with the provided requirements.txt one gets an error that there isn't a module pandas.core.index

I'm happy to fix this in one of two ways:

1. fix the requirements file to state that pandas must be <2.0.0 
2. fix the requirements file to >2.0.0 and fix the imports.

Thoughts?



**What is the exact command that was run?**
```
kb 
```

**Command output (with `--verbose` flag)**
```
