2. Add few high-level functions for managing directory:

2.1 Looking for file name: fat_directory_lookup_name
2.2 Looking for short file name entry: fat_directory_is_sfn_exist
2.3 Expand directory by adding cluster: fat_directory_expand
2.4 Write directory entry: fat_directory_write_dentry
2.5 Looking for chain of free entries: fat_directory_lookup_free
2.6 Create short name from long name: fat_directory_create_sfn
