allow for customizing FootNoteSectionHeading level

[cwlls]

If the user specifies a section heading string that starts with a properly formatted heading level it will be used instead of the default H1. Resolves #27.

Thanks so much for the PR! I'll check it and add it to the next version.

Is this coming soon? I'd really like my footnotes to be H2 instead of H1. Thanks 🙂

Edit: I just remembered that I can just change the file myself. Open source FTW. Thanks @cwlls for the code!

@DanMundy Sorry about the wait on this PR. The Obsidian devs are currently making a bunch of much-needed improvements to how footnotes are created and displayed (which I have listed here: #42 ). I am holding off changes until these play out in a few months to see where the plugin will best fit in then.
