Hashing

Hashing the files after extracting the cards from them allows inka2 to skip them on next inka2 collect command, if their content hasn't changed. This makes the program faster (especially when you use the inka2 collect command on a folder containing many Markdown files).

The -f/-full-sync flag allows you to collect cards from the file, even if it hasn't changed since the last time you used the inka2 collect command:

inka2 collect -f path/to/file.md
