Implement a helper class for Argo GDAC snapshot DOI access and discovery
from argopy import ArgoDOI
doi = ArgoDOI() # If you don't know where to start, just load the primary Argo DOI record
doi = ArgoDOI('95141') # To point directly to a snapshot ID
doi = ArgoDOI(hashtag='95141')
doi = ArgoDOI().search('2020-02') # Search doi closest to a given date
doi = ArgoDOI().search('2020-02', network='BGC') # Search doi closest to a given date for a specific network
doi.file # Easy to read list of files associated with a DOI
doi.dx # http link toward DOI resource
Closes #283
