panics if before_help is set

[jyn514]

i have a CLI tool that sets before_help to a non-empty string. when i try and use clap_markdown to generate markdown help, it panics:

thread 'main' panicked at /home/jyn/.local/lib/cargo/registry/src/index.crates.io-6f17d22bba15001f/clap-markdown-0.1.3/src/lib.rs:241:5:

it would be nice for this to be supported so i don't have to work around it in my own code.

looks like this would be fixed by #16

This should be fixed in the latest clap-markdown 0.1.4 release, just published 🚂
