Standardize field names in biophysical tables

[davemfish]

If a biophysical table is an invest input that has a row for each landcover type, then all tables need a landcover column. Most models call this column lucode, but some do not:

• Habitat Quality: lulc
• Coastal Blue Carbon: code
• Crop Production: this one is kinda weird. There is a whole table devoted to mapping lucode to crop_name, and then the biophysical table (fertilization rate table) uses crop_name. Probably there is a reason for this, so maybe it's okay not to touch it.

I propose we change to lucode. And I guess that would be a breaking change so should go in a minor release.

This would be a very satisfying change. 👍

I think the cropname one is because there's a standard set of crops that the model supports, and so it's letting you map your arbitrary LULC classification to that fixed crop classification

Just adding a +1 to this. For some reason, it's only today that I noticed that HQ uses "lulc", and was about to file an issue asking for it to be matched to the others that use "lucode", but @davemfish is already on it!
