Reformats Roam Markdown output for publishing via Hugo or similar

deroamify.py

# Takes exported Roam input and turns it into a better format for publishing.
# Output is still Markdown, but it's one that doesn't support backlinks.
# Good for traditional blogs.
# Run from a directory with a source .md file.
# Pipe output to a new file, i.e., output.md
