Removing pasture suitability calibration from calcPastureSuit.R from the preprocessing

[mppalves]

Changes summary:

• Updated cell area calculations by using land initialization areas instead of raster area calculations.
• Removed the script section that calibrated pasture suitability areas projected with historical values.
• These changes do not alter the output format; thus, MAGPIE remains functional regardless of the input generated. This is a minor improvement and the calibration removed from the preprocessing is now performed at the preloop stage of MAGPIE calculations.

Hey Marcos,
that looks all really good :) I added some comments.
I guess the only think where I would ask you to check is LN:96, the rest is kind of optional.

cool that you found time to fix this :)

the reordering and cell renaming looks suspicious to me and should be removed if possible. Rest looks good to me

looks good. Just fix the merge conflicts and build again and you should be from my perspective ready to go

I just had a quick look if my comments have been addressed and it looks very good :)
Thanks Marcos for addressing everything. Good to go from my side :)
