[victorlin]

Major refactoring to add rdrp data explorer

Live preview:

• current nucleotide explorer: https://dev-rdrp.serratus.io/explorer-nt
• rdrp explorer: https://dev-rdrp.serratus.io/explorer-rdrp

ref #79, #112

Progress

• [x] query builder
• [x] add GenBank titles back
• [x] add theme colors from #120
• [x] add link in /geo
• [x] rdrp: Intro component
• rdrp run result
  • [x] use family_group
  • [x] add pagination to run searches
  • [x] rdrp run result buttons: SRA, Trace, .pro, .summary
    • s3://lovelywater/rpro/X.pro.gz
    • s3://lovelywater/rsummary/x.rsummary
• [x] rdrp result: update colMap config object
• [x] nucleotide: add jbrowse links back as icons
• [x] fix 500 error on API when directly loading run query
• [x] update endpoints
  • ~use endpoint /explorer/rdrp~ can't due to #127
  • use endpoints /explorer-nt, /explorer-rdrp
  • redirect /explorer -> /explorer-nt for links in manuscript

Other improvements along the way

• rename genbank to sequence internally (peer PR serratus-bio/serratus-summary-api#17)
• remove brackets from URL search params
• restore selection on dropdown close
• add context for each search type
• two D3 charts for run lookups
• start creating class definitions for result charts (work in progress)
• remove old data scripts

• Alignment identity should be a sliding window from 45% - 100% for RdRP, 75% is too high for amino acids and will miss a good chunk of data.

• We do not need a phylum level of search, this is too broad and non-specific. Family is the highest functional level.
