Handle the DA:ALL column header in MIDAS files

[nanls]

Hi,
Thanks for your tool.

In caspots, you are currently retrieving the time steps in caspots/dataset.py (l. 142) using

time = int(row.get("DA:%s" % var))

The documentation of CNO (https://saezlab.github.io/cellnopt/6_CNODocs/) mentions a DA:ALL column header for the cases where all the species have been measured at the same time step.
With the current version of the code, using DA:ALL leads to the following type error :
TypeError: int() argument must be a string or a number, not 'NoneType' because the var variable does not exist, so nothing is catch by the row.get, so the integer casting cannot be done.

Hence, I propose the following modification for it to handle it :

try:
    time = int(row.get("DA:%s" % var))
except (TypeError):
    time = int(row.get("DA:ALL"))

Best,

nanls
