find_files_and_readers read unneeded files

[mraspaud]

you might need to indicate a time also in find_files_and_readers to load just one set of files at the time.

I found it better to separate my favorite files in another directory, instead of indicating the time range. Because find_files_and_readers seems to read all the files, whether or not being indicated in the time range.

I do not think if find_files_and_readers ignores start and end times. Rather, it cannot efficiently apply the time range.
For example, suppose we have 100 files and we want to plot only 4 of them. Instead of reading and plotting exactly those 4 files, find_files_and_readers takes considerable time to read (not plot) all of the 100 files for plotting those 4 specific files. Therefore, it wastes time in reading 96 extra files.

Thanks for the clarification.

I no longer see this problem in Satpy version 0.33.1. find_files_and_readers exactly reads only those files in the time range.
