Integration ICASA standard

[HGarre]

Think about whether to use the ICASA data standard (at least some variable names) for agronomic data in ODMF : https://github.com/DSSAT/ICASA-Dictionary/blob/main/ICASA%20Data%20Dictionary.xlsx. If desired, create a code to upload data directly from an ICASA standard datasheet to ODMF and/or download data from ODMF into an ICASA data sheet.

Current way of integration:
-When adding new value types, have a look to the latest ICASA dictionary (https://github.com/DSSAT/ICASA-Dictionary/blob/main/XLSX/ICASA_Data_Dictionary.xlsx) an pick out the corresponding variable_name and unit. When variable_names in ICASA are aggregated over a day (e.g. maximum_temperature), use a non-aggregated equivalent (e.g. temperature) to make subdaily entries possible and add a comment as explained below
-To all value types (exsiting and new) to which corresponding ICASA variable_name(s) exsits, a comment will be added. More than one corresponding variable_name can be added.
General Format:
ICASA: variable_name*unit_conversion_factor, summary_function (causion the "*" is required, do not use /x but *1/x)
unit_conversion factor: variable_name[unit]conversion_factor = valuetype[unit]
summary functions: python language, mostly mean, min, max, sum
conversion factor and summary function are optional
Example: "Air temperature[°C]" (ICASA daily aggregates):
ICASA: temp_avarage_daily, mean
ICASA: maximum_temperature, max
ICASA: minimum_temperature, min
Example "Grain yield" [kg/m2] (ICASA unit kg/ha)
ICASA: harvest_yield_harvest_dw*0.0001
