Change expected input of www/ir and mmm/ir tables

[sgwinder]

Improve integration with viz-model by changing the column names that trails-viz expects in the www, wwwir, mmm, and mmmir tables.

wwwir

Current Column	Proposed Column	Reason
trail	siteid	Consistency
resp.ss	weekly_viz
resp.ll	days_ir_pc	This column currently shows "days of data". In viz-model, I'm writing out a few relevant columns: days_ir is days of IR counts, days_pc is days of parking lot counts, and days_ir_pc is the sum. Though note that I am using that amount of data, but then extrapolating to get estimates of total visitation for the week
resplg	drop	We're not displaying this anywhere on the dashboard, so it's not necessary
d2p	weekstart	This one is ok... I've replaced it in viz-model with weekstart because this is more informative for me. I've been calculating d2p as weekstart + 2, so this would also be ok

mmmir

Current Column	Proposed Column	Reason
trail	siteid
resp.ss	monthly_viz
resp.ll	weeks_ir	monthly_viz is NOT like weekly_viz, in that we are simply adding up visitation from the weeks that we have estimates for. So weeks_ir is important for saying how many weeks went into this sum.
resplg	drop

Social media tables

• Possibly switch from "flickr", "twitter", "instag", and "wta" to PUD, TUD, IUD, and WUD

www

Current Column	Proposed Column	Reason
trail	siteid
jjmm	modeled_viz	Or something like this, that's more interpretable than jjmm
jjmmlg	drop
d2p	weekstart
	model	I've been writing out the name of the model used to create the estimates
	datecreated	And the date that I did that round of modeling

mmm
Same suggestions as www, but keeping d2p as is.
