From<fastcgi::Request>: Convert HTTP headers

The HTTP headers from `fastcgi` come with keys in the following format:
"HTTP_USER_AGENT", "HTTP_ACCEPT_LANGUAGE".

Since most headers use an uppercase first letter of a word with hyphen
word separators, make the conversion by:

1. Removing the `HTTP_` prefix
2. Changing `_` to `-`
3. Making the first letter of each word uppercase using the Inflector
   crate
