LIMS-2159: Allow CSV upload of ligands

[ndg63276]

JIRA ticket: LIMS-2159

Summary:

Add a CSV uploader for ligands. As ligand info often comes in a fairly rich spreadsheet, we should be quite flexible with column names.

Changes:

• Fix page count and sorting of ligands on ligand view page, allow searching by fields other than 'name'
• Allow adding of multiple ligands in a loop in the backend
• Enforce install of papaparse library to inspect CSV files (previously installed as a dependency of csv-file-validator anyway)
• Add a radio box to switch between CSV upload and single mode on the ligand add page
• Make different fields compulsory in each mode
• Parse the header lines in the CSV to try to get "Name", "Source Well" and "SMILES" columns, or similarly named ones
• Display errors if found, add notification on upload success, and redirect to the View Ligands page

To test:

• Go to any proposal (eg mx23694), go to Ligands in the main menu, then click Add Ligand(s) to go to /ligands/add
• Choose "Add a Single Ligand" and fill in the name field and any others you fancy, click Add Ligand(s) and check you are redirected to a view of your ligand
• Go back to /ligands/add, and choose CSV Upload. Check only 3 text boxes remain visible (and are compulsory), as well as the file selection box
• Go to LIMS-1052 and download any of the spreadsheet files (except Euopen_screen_with_smiles.xlsx), then export it to CSV
• Select the CSV on the /ligands/add page, check no errors occur. Click Add Ligand(s) and check it uploads ok, and you are taken to the View all Ligands page
• Check searching for Ligands and ordering by clicking on the headers works ok
• Delete the Name or SMILES code from one line of your CSV, and then try to re-select it on the Add Ligands page, check your are shown an error explaining which line number has a problem

It seems to work OK, but it times out whenever I upload a CSV. It still comes through, but I don't get redirected at the end
