Add a quick format option for mkfat32

Browse source 
Added open implementation

Needed to return a pointer to the file system as `@fieldParentPtr(Fat32Self, "instance", fs.instance)` doesn't work as the the pointer to `instance` is on the stack, then goes out of scope when the init is returned. So will be using free stack space.
Part of #216

Spelling, doc comments and extra test for open file


init -> create, deinit -> destroy
