Enhancement request: Swifter to label .wasm files as "application/wasm" when it serves them

[SugarRayLua]

Dear Swifter Developers,

I am a novice javascript user who uses the Swifter tiny http server engine in the iOS app "World Wide Web Sever". It would helpful in the future if Swifter labeled .wasm files as MIME type "application/wasm" when it serves them to help browsers do .wasm instantiate streaming.

Thank you for the considering this enhancement. :-)
