Support integrity hashes

Support retrieval of integrity hashes (SHA-256) for content hashed paths.

Usage:

output := hashedFs.GetHash("/path/to/file.js")
fmt.Println(output)
// Output: 8d77f04c3be2abcd554f262130ba6c30f277318e66588b6a0d95f476c4ae7c48

Changelog

• Added new HashedFs.GetHash(path) function to retrieve the integrity hash (SHA-256) of a path
• Modifed FileHasher interface to allow retrieval of the algorithm

v0.0.2
