Create proper config for "hindcastonly" mode

[wwlwpd]

hindcast only consists of:

• don't nowify
• select final advisory as start and ending
• provide support for the calculation of the following:

HINDCASTENDDATE=2004091100
HINDCASTLENGTH=30.0
COLDSTARTDATE=2004081200

Notes:

• the COLDSTARTDATE is HINDCASTENDDATE - 30 days
• you first calculate the base time which is essentially the landfall date + the landfall time rounded (no minutes)
• the theoretical run start is the same as the base time but always ends with 00
• if you find find this theoretical run start in the advisory list in noaa website you take that as an ASGS RunStartTime which is the same as **HINDCASTENDDATE**
• if you don't find it in the list you take the first available date and time minus 3 hours
• landfall date is determined by what was documented at the Time ([Stratos] has detailed links of all the documents that say when landfall was observed)

Made a move towards supporting this, peared off storms into their own YAML file that is now in the repo.
