webtransport api

[crotwell]

Webtransport is new protocol that might be compelling alternative to websockets at some point in the future:

Not proposing as a shortterm feature as likely more complicated to implement, but has features that might be appealing for seismic data delivery someday, like unreliable delivery for display purposes, better backpressure handling, and maybe speed improvements.

Consider this a placeholder/reminder...

WebTransport requires HTTP/3, which is a wholly different beast than the currently supported HTTP/1.1. The future where WebTransport is supported likely coincides with the same horizon where I re-write ringserver in Rust and can rely on external crates for HTTP/WebSocket/TLS/regex/etc.
