Ability to define number of different types of compressed plots per destination archive drive

[toto99303]

Hello, thanks for the awesome script, much appreciated!

I have a proposition for enhancement for the archiver:

• ability to define number of different types of compressed plots per destination archive drive.

Example:
4TB drive can have 47 C7 plots or 30 C6 + 17 C7 plots. The latter is more efficient as you're farming the same number of plots, but mostly with lower compression (power)
Thus when plotting you need to be able to spread all ready-made C6 plots across say 10 drives, exactly 30 per drive. And then exactly 17 C7s per drive, too.

Thanks!
