add post-downscaling wet day correction in the workflows

[emileten]

@brews I went ahead and added changes to make use of the option developed here ClimateImpactLab/dodola#141. From the biascorrectdownscale template, I passed over the already existing correct-wetday-frequency parameter onto the qplad template, then within it to with-lat-chunks and within it to apply-qplad. At that point the value of the parameter is passed to the boolean click option --wet-day-post-correction. How does this sound to you ? I was thinking about testing that in an actual e2e-pr workflow run, but I wanted your input first.

Also -- I think that's for @dgergel -- note this means there isn't an option to apply this correction only pre or only post downscaling, it arbitrarily does both. Is that ok ?

[dgergel]

@emileten it's fine if the pipeline only does both, as there isn't a situation in which we'd want to do either/or. We do want it only for precip, but I don't think you changed that so that's okay.

@brews would be great if you reviewed this too before we merge.

Nice! @emileten This is going to need a few changes. I'm going to move this into a "draft" PR, until we walk through how to test and run the dev releases of dodola, @emileten, then we can review this.

@brews is this needed to run a "correct" e2e precip workflow?

[emileten]

@brews I think I fixed one problem with this, not sure it was all or even part of what you were worried about.

Back then I added the correct-wetday-frequency option to qplad.qplad. But not to qplad.main (entrypoint) which under the hood calls qplad.qplad. Without no default value specified anywhere, a qplad workflow running from its entrypoint would have crashed.

So, the few commits above I think should fix this.

Appreciate this contribution, @emileten ! I think this is good to go. 👍

[brews]

I'm going to merge this and begin testing now that we've got some precipitation data to play with from #485.
