Modify fetching utility to retrieve png files

[ljlamarche]

Although mangopy is designed to use the full night hdf5 files, some users may want to work with the more traditional png image files. Should we add functionality to fetch all the png image files for a particular night?

That is a good idea.

I can look into adding this for the second release. I think we can use a very similar protocol as our current data fetching if there's a way to get a list of file names. ftplib (https://docs.python.org/3/library/ftplib.html) may be a good option to consider.

from ftplib import FTP
ftp = FTP('isr.sri.com')
ftp.login()
ftp.nlst('pub/earthcube/provider/asti/MANGOProcessed/Rainwater Observatory/Oct0116')
