Description
While I love that there are very few configuration options, since there are some, what do you think about having the CLI read a configuration file in addition to the arguments that are passed in?
In most cases, it's not too much effort to make sure you're passing in the options you want (and I particularly like the ability to dynamically define rake tasks with the options already specified!), but that becomes a bit unwieldy with multiple projects that use different options. E.g., the VS Code extension lets you specify those options, but they're applied globally. Switching projects means I need to remember to update my editor to match the options for syntax_tree. Having a per-project config file would let that (and other) editor integrations "do the right thing" in each repo.
If you're open to it, I'd be happy to make a pass at implementing the necessary changes.
