fmuobs - Non-unique observation labels when converting from resinsight to ERT obs format

[asnyv]

The ResInsight format does not have labels, and a label is made based on the key (vector name). This is not unique if multiple observations are present for the same key (vector), and ERT doesn't like that.

subscript/src/subscript/fmuobs/parsers.py

Line 465 in d0f04a1

dframe["LABEL"] = dframe["KEY"].astype(str) # + "-" + dframe["DATE"].astype(str)

There is a commented part of the line which adds the date, which is an option. Another alternative is to add an index like what is done for the yaml based format:

subscript/src/subscript/fmuobs/parsers.py

Line 505 in d0f04a1

rowdict["LABEL"] = keylist["key"] + "-" + str(obs_idx + 1)

An index is maybe the best to be consistent with the behavior of the yaml based.
