Enhance TC-Gen to print warnings about duplicate genesis events for the same storm.

[JohnHalleyGotway]

Describe the Enhancement

When running TC-Gen, Dan Adriaansen found a discrepancy between the number of BEST track genesis events reported (209) versus the number of unique lat/lon locations listed in the log file (202). Genesis at the same lat/lon location and time were counted twice seven times. In all 7 cases, genesis was identified both in the INVEST and the numbered storm. This can easily be avoided by ignoring the INVEST track files or by setting a minimum category threshold, such as:
category = [ "TD", "TS"];

To make the code more user-friendly, identify these situations and print a warning message about them. Then the user can decide how to proceed.

For example, the first duplicate occurs in these 2 files...
kiowa:/d1/dadriaan/projects/s2s/tc/data/weiwei/obs/allvigh> egrep "119N, 1416W," b*
bcp012018.dat:CP, 01, 2018092618, , BEST, 0, 119N, 1416W, 25, 1008, DB, 0, , 0, 0, 0, 0, 1009, 180, 50, 0, 0, , 0, , 0, 0, INVEST, ,
bcp972018.dat:CP, 97, 2018092618, , BEST, 0, 119N, 1416W, 25, 1008, DB, 0, , 0, 0, 0, 0, 1009, 180, 50, 0, 0, , 0, , 0, 0, INVEST, ,

And the second duplicate occurs in these 2 files:
kiowa:/d1/dadriaan/projects/s2s/tc/data/weiwei/obs/allvigh> egrep "145N, 832W," b*
bal142018.dat:AL, 14, 2018100418, , BEST, 0, 145N, 832W, 20, 1007, DB, 0, , 0, 0, 0, 0, 1009, 100, 90, 0, 0, , 0, , 0, 0, GENESIS036, , 0, , 0, 0, 0, 0, genesis-num, 036,
bal912018.dat:AL, 91, 2018100418, , BEST, 0, 145N, 832W, 20, 1007, DB, 0, , 0, 0, 0, 0, 1009, 100, 90, 0, 0, , 0, , 0, 0, GENESIS036, , 0, , 0, 0, 0, 0, genesis-num, 036,
