Optimize binary size about sxg-rs HOT 2 OPEN

I was wrong about table[0]. Useful output is available in a dev build, e.g.:

(cd cloudflare_worker; ~/.cache/.wrangler/wasm-pack-0.10.0/wasm-pack build --target no-modules --dev) && twiggy dominators cloudflare_worker/pkg/cloudflare_worker_bg.wasm | less

or likewise twiggy top

from sxg-rs.

The wasm is reduced from 1.2 MB to 993 KB by removing disabling the pem parsing code

 fn get_der(pem_text: &str, expected_tag: &str) -> Vec<u8> {
+    return vec![];
-    for pem in ::pem::parse_many(pem_text) {
-        if pem.tag == expected_tag {
-            return pem.contents;
-        }
-    }
     panic!("The PEM file does not contains the expected block");
 }

We could find an alternative pem parser that takes less than 240 KB.
