Option to exclude files/folders

[patrickwolf]

Synology creates a @eaDir folder in every folder and a #snapshot folder at the root.

Would be great if they were excluded by default or could be excluded via cmd line

Here a list of files that can could be excluded by default https://github.com/rsgalloway/hashio/blob/db14a1aab73e1c96ad4abf50c1c27baee3dc9187/lib/hashio/config.py#L69C1-L101C2
