Version 0.3.2. Features: * Add `format_volume` function for initializing a FAT filesystem on a partition * Add more checks of filesystem correctness when mounting Fixes: * Clear directory returned from `create_dir` method - upgrade ASAP if this method is used * Fix handling of FSInfo sector on FAT32 volumes with sector size different than 512 - upgrade ASAP if such sector size is used * Use `write_all` in `serialize` method for FSInfo sector - previously it could have been improperly updated
