LIMS-2228: Move hmap and caman out of vendors folder

[ndg63276]

JIRA ticket: LIMS-2228

Summary:

There are a few JS libraries manually inserted into the vendors folder, they should be moved to package.json if possible.

Changes:

• Remove heatmap file, remove alias, add heatmap.js to package.json, update imports
• Remove caman file, remove alias, add caman-dist-only to package.json, update imports and manually declare Caman
• Don't install http or fs as part of caman, update imports-loader so caman knows we are running in a browser
• Remove backbone.syphon file, update imports (backbone.syphon was already in package.json)
• Remove unused luxon import, luxon was removed in LIMS-2044: Remove luxon #1022

To test:

• heatmap.js:
  • Go to a container with grid scans (eg /containers/cid/379691, well B8d2), check the results heatmap is still displayed
  • Go to a recent grid scan (eg /dc/visit/cm44138-3/id/24524776), check the results heatmap is still displayed
• caman:
  • Check the diffraction viewer still works on the grid scan
  • Go to a rotation data collection (eg /dc/visit/cm44138-3/id/24524800), check the diffraction image viewer still works
• backbone.syphon
  • Go to a SAXS proposal, eg cm44173, check you can still make a shipment and a puck within it (you may need to make a protein first)
