Change EncrytedFs::read_dir/plus to only show children

[someotherself]

The fs_api layer must allign with rust standard library.
std::fs::read_dir only iterates over children. Ours should do the same.
Changes are needed for:

1. encryptedFs function,
2. tests for encryptedFs and for Path
3. docs for Path method

Hey! I was trying out both on my system. I see Directory Entry for Encrypted::fs and DirEntry for rust std::fs. What do you mean by align our api to iterate only over children? Can you explain with below example?

When running std::fs::read_dir, (I'm testing it on linux and windows) it will only iterate over children and ignore . and ...
read_dir and read_dir_plus in our EncryptedFs current include . and ...
In your example, ino: 1 is root (or parent) dir - .. When running fs.read_dir(1), it should show only the RegularFile.
This is not exactly a bug however, our own fs_api::fs::read_dir will be using these functions and we want it to be 100% interchangeable with std library.
Are you getting a different behaviour out of std::fs::read_dir?
