Decode Packets, Again (#1156)

* fixing issue where the iterator of a closed stream produces no output; added option to include an entire directory of input files; streamlined workflow between gcapy and preprocessed files

* added documentation; restored functionality of the source's iterator; tidied code

* restored functionlaity/reliability of skip-existing and management of duplicate files and file cleanup; added exclusive log for decode error messages

* collects all literal decode errors falling through the logging cracks

* finally eliminating log spam; tidying up the decoded log files's format

* better subclassing and management of the decoy OutStream

* tightening of the noose

* fixing the readme to account for the -f flag

 Now you can run the program like that:
 ```
-psf-decode-packets -o ./output-directory foo.gcap bar.gcap
+psf-decode-packets -o ./output-directory -f foo.gcap bar.gcap
 ```
 By default, decodePackets takes in `.gcap` files, but it can also take gcapy ascii files with the
 `-p` option. Run `psf-decode-packets --help` to get usage info.
