pysat stores filenames in the user_home/.pysat directory. Returns
a list of all new fileanmes since the last known change to files.
Filenames are stored if there is a change and either update_files
is True at instrument object level or files.refresh() is called.
Returns
-------
pandas.Series
files are indexed by datetime

Produces a list of files and and formats it for Files class.
Requires fixed_width filename
Parameters
----------
data_path : string
Top level directory to search files for. This directory
is provided by pysat to the instrument_module.list_files
functions as data_path.
format_str : string with python format codes
Provides the naming pattern of the instrument files and the
locations of date information so an ordered list may be produced.
Supports 'year', 'month', 'day', 'hour', 'min', 'sec', 'version',
and 'revision'
Ex: 'cnofs_cindi_ivm_500ms_{year:4d}{month:02d}{day:02d}_v01.cdf'
two_digit_year_break : int
If filenames only store two digits for the year, then
'1900' will be added for years >= two_digit_year_break
and '2000' will be added for years < two_digit_year_break.
Note
----
Does not produce a Files instance, but the proper output
from instrument_module.list_files method.
The '?' may be used to indicate a set number of spaces for a variable
part of the name that need not be extracted.
'cnofs_cindi_ivm_500ms_{year:4d}{month:02d}{day:02d}_v??.cdf'
