config file (as in gitconfig or sublimetext) to configure macdown

Could we have a config file (eg: .macdown) to configure the various options of macdown (eg: View>Renders TOC) ?

Even something barebones and subject to change as a start would be great. It's a lot easier to edit a config file (and share it online) than to click on menu items (and more cross-platform too). It also should be easier to implement/maintain and to discover the available options for the user.

Search path could be same as gitconfig (ie a global one, which can be overridden by searching in parent directories)

Format could be json (as in sublimetext) or gitconfig like

https://github.com/uranusjr/macdown/issues/395 also proposes other config file options which would be useful
