JASPER 268: Fix Criminal-document download functionality

[JTraill]

Pull Request for JIRA Ticket: ----268----

1️⃣ Use our own base64url logic utilizing btoa 0️⃣

The package we currently rely on to base64 our urls has issues regarding latest JS frameworks.
This PR forgoes that package and uses our own base64url functionality.

We should at some point completely deprecate this package from the project and use the method I introduced here.

fix: criminal document download functionality
refactor: remove unneeded error handling from courtfilesearch
refactor: prettify shared.ts
build: remove if exists flag from unit-tests in FE build

Fixes # 268
