Accepts a message pack string or a file object, renders said data back to
a python dict.
.. note:
This renderer is NOT intended for use in creating sls files by hand,
but exists to allow for data backends to serialize the highdata
structure in an easily transportable way. This is to allow for more
fluid fileserver backends that rely on pure data sources.
