Simple HTTP Server for serving wasm files

Extends python3's http.server.SimpleHTTPRequestHandler to add custom headers and mimetypes required to serve the wasm files.

By default server listens at port 8080

~/httpserver-wasm  ➟ python3 server.py
HTTP Server listening at port 8080 ..

Change the port by setting env PORT

~/httpserver-wasm  ➟ PORT=9090 python3 server.py
HTTP Server listening at port 9090 ..
