 # 2018-Feb-15: Fix, add 1 hour when showing the next date you could issue a cert when hitting the rate limit. This is because Let's Encrypt always issue the certificates using 1 hour less than real time but Let's Encrypt keeps the real time in their DB to remove expired limits (v0.13)
 # 2018-Apr-16: Enhanced, added column CERT TYPE to show whether the logged cert is the Final cert or the Pre cert. Due LE is embeding SCT receipts in certificates, the certificates are logged twice, the pre certificate and the final cert with the embeded SCT receipts. As Final certificates are logged a few hours or days after the pre certificate, the script only takes care of pre certificates to check them against the rate limits (v0.14)
 # 2018-Apr-16: Enhanced, added options [-p|--pre] and [-f|--final] to show only Pre certificates or to show only Final certificates. If no option, script will show both types of certificates. The rate limits using -f option could not be accurate due this type of cert takes too long to be logged. Rate limits using --pre option or none are counted using only the logged pre certs (v0.15)
