Explicit return on routes

[dorronso]

Awesome job. Whilst tweaking the project to suit my personal requirements I have come across this: (https://www.fastify.io/docs/latest/Reference/Routes/#async-await):

In this case do not forget to return reply or await reply in your async handler or you will introduce a race condition in certain situations.

Although I have not experienced race conditions, I was wondering if it would be necessary to return reply on ohif routes. (https://github.com/knopkem/dicomweb-proxy/blob/e3ef28aff1a81139c9dcbd79c6825dde2b4c7df2/src/routes/routes.ts)
