feat: add ability to build ts|tsx from node_modules

[puehringer]

Migration guide for Node 20 and no_dist:

First, create a no_dist branch and do the following in the package.json:

• Replace all of our dependencies with the #no_dist branch
• Update the exports/main/types fields. This has to be done according what is already exported, but if no exports field exists, you the following:

  "main": "src/index.ts",
  "types": "src/index.ts",
  "exports": {
    ".": {
      "types": [
        "./dist/index.d.ts",
        "./src/index.ts"
      ],
      "import": [
        "./dist/index.js",
        "./src/index.ts"
      ],
      "default": [
        "./dist/index.js",
        "./src/index.ts"
      ]
    },
    "./phovea_registry": [
      "./dist/phovea_registry.js",
      "./src/phovea_registry.ts"
    ],
    "./dist/phovea_registry": [
      "./dist/phovea_registry.js",
      "./src/phovea_registry.ts"
    ],
    "./dist/scss/*": [
      "./dist/scss/*",
      "./src/scss/*"
    ],
    "./package.json": "./package.json"
  },

• Switch to Node 20 using nvm use 20.9 (this should be the default! Uninstall all other node versions using nvm uninstall ...)
• Then install and test using rm -rf yarn.lock node_modules && yarn && yarn run all && yarn webpack:prod && yarn start dev_server_only=true
• In the end, make sure to create a PR and link it in the repo sheet (see Node20 and no_dist column)

If you encounter any issues, please report them.
