Delivering HTML-, JSON and other files

[cheetahbyte]

I think Ermine needs something that is able to deliver HTML-Files. At the moment the only option is to either take the HTMLResponse which accepts the HTML Content as a string (you need to read the file manually) or to take FileResponse, where you have to set the Content-Type Header manually for the browser to render your html properly.

There should be a solution like:

@app.get("/")
async def home():
    return HTMLFileResponse("/path/to/html/file")

the same applies to other files like JSON and so on.
I think that generic filetype responses should be included, for easier use of ermine.
