blake3 code is used in several places on the code. The file was duplicated on root and rbf package. To avoid cyclic dependencies, I moved it to hash package. Some methods must be public to use them in different places. HashOfDir method was removed. Not used. Signed-off-by: Antonio Navarro Perez <antnavper@gmail.com>
