Support Frictionless Data package as a source of metadata

[ludovicc]

Frictionless Data specifies a json format to describe a list of data files (csv) and their schema. It can describe primary keys, foreign keys, field types and constraints. This information looks very similar to SDV metadata and it's available in many datasets. Could SDV convert it to its own format?

Great suggestion, @ludovicc !

We could definitely look at adding options to load them into our Metadata class.
