deprecate convert_to_wide

[kellijohnson-NOAA]

@k-doering-NOAA do you think that we can remove

ss3sim/R/get-results.r

Line 613 in eeb0b33

convert_to_wide <- function(lng) {

Seems like the long results have been around long enough that we might not need to provide support for the "old" way.

I'm not sure... sometimes it is helpful to have wide rather than long format for some plots. I'll have to think more about this.

@k-doering-NOAA just wanted to double check that {SSMSE} does not use type = "wide" because I am planning on deprecating this functionality this week. I searched {SSMSE} for "wide" and did not find it wrt {ss3sim} but I just wanted to make sure.

Thanks for checking, you are correct, {SSMSE} doesn't use type = "wide"
