Feature request: Add Expression as Region-Based Annotation

[berntpopp]

Description:
Integrate expression data, specifically for the adrenal gland, using region-based annotation from databases like UniProt. This will provide valuable expression information that can be beneficial for specific projects related to adrenal gland research. Utilize the functionality implemented in another issue (Feature request: Add Gene or Region-Based Annotation using SnpSift Intervals #5) and generate the required BED input files for the annotation.

Tasks:

1. Update Configuration File:

   • Add paths for expression data annotation files in config.yaml.
   • Define fields for each expression data annotation in the configuration file.

2. Utilize Existing Snakemake Rule:

   • Use the rule for annotating with interval files from Feature request: Add Gene or Region-Based Annotation using SnpSift Intervals #5.
   • Generate required BED files for UniProt adrenal gland expression data.

3. Documentation:

   • Update the README to include new configuration options and usage instructions for expression data annotations.
   • Document the new rules and their purpose within the script.

Additional Context:
Incorporating expression data specific to the adrenal gland will add valuable context to the VCF files, providing insights into gene expression relevant to adrenal gland research projects.
