Multiple parameters & append mode enhancement

[DavidBalas1]

Changes:

• Added an option to receive multiple parameters to replace to by a wordlist, usage example: Get all urls matching xss patterns, and replace each parameter by multiple parameters given by a list of payloads.

cat urls.txt | gf xss | qsreplace -w xss_payloads.txt | ffuf ..

• Added an option to run qsreplace with and without appendMode in one run, qsreplace will once replace the parameters in the url and once append to the parameters in the url, usage example:

cat urls.txt | gf xss | qsreplace -b "payload" | ffuf ..

• qsreplace will now skip urls with no url parameters.
