Allows to change behavior of `deno fmt` to use "ASI" setting for
semicolons instead of always prefering them, this is done
by "--options-semi=asi" flag or `"semi": "asi"` setting
in the config file.
This flag disables loading of configuration file, ie. it will not be
automatically discovered and loaded. Of course this flag conflicts
with "--config" flag and they cannot be used together.
