[feature] Create a data loader for ARGO profiles

[b-barton]

Is your feature request related to a problem?

We need an ARGO data loader.

Describe the solution you'd like...

Load the AGRO profile data. We need latitude, longitude, time and assign a profile_id which needs to be unique to each profile. Format the data something like this:
profile = xr.Dataset(
{
"lon": (("profile_id"), profile_lon),
"lat": (("profile_id"), profile_lat),
"time": (("profile_id"), profile_time)
},
coords={
"profile_id": prof_id,
},
)

Test the data is loaded and in the right format for the sampler.

Describe any alternatives you've considered...
