• Calculate depths from BAM files if Mosdepth per-base.bed.gz not found.
• SolidJS instead of JQuery for UI
• Migrated to Typescript and TSX from JS for frontend code.

• Fixed variant bar colours to represent ALT allele rather than REF.
• Simplified CLI options with auto-detection of files and parameters based on type of analysis results provided.
• Coverage depths are compressed by default to base64 encoded string in HTML output to reduce HTML output size.
• Added more coverage plot visual customization options for colours, fonts, sizes, etc.
• Removed Jest JS/TS testing for now.
