Fix persona images not being added as Base64 (#84)

* Made some adjustments that the pictures in the persona get converted to Base64 strings versus loading it remotely from Canvas (as the access key is only valid for a limited time period) * Add coding guidelines enforcement (#85) * Add initial coding guidelines and fix where necessary * Enforce code styling and update code where necessary * Remove duplicate .editorconfig entries * Add code analysis setup to CI * Add missing checkout step * Update incorrect action version tag * Remove incompatible analysis step * Push code style offense to validate CI pipeline * Remove code style violation * Add global.json * Made a couple of changes based on recommendations made in the merge request. --------- Co-authored-by: Jelle Maas <typiqally@gmail.com>
