Stored nodes have encoded values with at least uncompressed commitments and children hashes. All (little-endian) bytes are also tail truncated to compress their representation. Furthermore, null nodes are represented by empty bytes (0x80 in RLP encoding). The commit also includes a major refactoring of location attribute for nodes. Previously, leaf location was their full key, which was a little awkward. Now, node location is truly its location in the trie, no matter what kind of node it is. Among other things, this means that we store a StemNode's depth along its stem, so we can retrieve its location. Coming up is the possibility to store commitments in compressed form, which would save a lot of space (50% on commitments). Signed-off-by: Thomas Zamojski <[email protected]>

PR description
This is a continuation of the previous PR #65
It appeared that the previous PR had some bugs, and meanwhile it was decided to add stem extensions into the DB in order to be able to get stemNodes by stem without requiring a nearest request.
In this PR, InternalNodes include stem extensions into its encodedValues, useful to create the children Stored Nodes including their appropriate keys (location or stem). The key is then used to load the StoredNode.
StoredNode are also separated into Internal and Stem Nodes as well to reflect this difference.
