.bin extension files are served text/plain

[jl]

Files with .bin extension are usually served as application/octet-stream by most out-of-the-box web server and operating system configurations. This is useful for marking data as really binary data.

Example in golang:
https://cs.opensource.google/go/go/+/refs/tags/go1.26.4:src/mime/type.go;l=69

Currently, .bin files are served from pgs.sh as:

content-encoding: zstd
content-type: text/plain

I'm guessing it's from the GetMimeType function. It would be nice to add a case for .bin files:

func GetMimeType(fpath string) string {
	ext := strings.ToLower(filepath.Ext(fpath))
	switch ext {
	case ".bin":
		return "application/octet-stream"
	case ".svg":
		return "image/svg+xml"

In fact, GetMimeType() currently has no extensions which map to application/octet-stream.
