Reordering of monthly nightlights data required

[meghapatnaik]

To construct a radiance datacube, we may wish to use readdir() on a folder containing a series of consecutive monthly files. If readdir() produces chronologically ordered files, this will construct the correctly sequenced datacube. However, it is better to replace readdir() with readdir_nl(), which can extract the timestamp from the filename directly. Since night light files from EOG are sequenced as "sensor_satellitename_timestamp_ ...", in any instance a different satellite source is used for a monthly image, there will be no disruption in chronological ordering. Function that can be used to extract the date:

get_date_from_filename(filename) = Date(parse(Int, match(r"\d{8}", filename).match))

A similar solution has been proposed in pull request #41

Can you point to the lines that need to be changed? GitHub allows you to hyperlink a line, for example:

Karmana.jl/src/Karmana.jl

Line 7 in e0398ad

I cannot seem to hyperlink lines from pull requests that have not been approved (can you do the above for any line of read_nl.jl?).

I suggest we approve pull request #41 in entirety. lines 1-7 and line 20 in read_nl.jl and the corresponding change suggested in line 41 Karmana.jl to include read_nl.jl will solve the issue described.
