Suggestion: Latest pkl resume

[chrsmlls333]

I've come across @RoyWheels discussing non-square training on reddit and noticed he had reimplemented auto-discovery of the latest pkl in results folder, as well as parsing the kimg number from that filename.

@dvschultz Would you be open to a pull request of this? Is there a reason its not already implemented, as I remember your stylegan2 fork having this.

[dvschultz]

You’re welcome to PR this. I personally found people more likely got confused with the auto-discovery so haven’t implemented it myself.

I just pushed an update so that you can do all of this manually if you want this control without the auto-discovery

--nkimg: set start kimg count
--initstrength: set start augmentation strength
--resume: path to pkl

Okay no worries, that's why I asked. I won't change the arg default.

I'm a little confused on --initstrength, what is ideal behaviour to make resuming as close to continuous training as possible?

Testing feature branch now, I will shoot the PR soon. This will be my first one so bear with me, thanks.
