Feature Request: custom section ordering.

[jtk54]

I'd like to be able to reorder the sections of the clog output based on the .clog.toml file. As an example,

"Bug Fixes" = ["fix"]
"Features" = ["feat"]

would place bug fixes first and features second and

"Features" = ["feat"]
"Bug Fixes" = ["fix"]

would reverse the order. Is this doable now? Otherwise this would be great for those of us that are persnickety.
