fix UHSLC retrieval testcase

[veenstrajelmer]

It seems there is something wrong on the server side, the following error is raised when retrieving uhslc_id=3 (or 1 to 5):

HTTPError: Error {
code=404;
message="Not Found: Your query produced no matching results. (uhslc_id=3 is outside of the variable's actual_range: 6 to 915)";
}

According to the legacy data portal, there is a station 3 (Baltra) present that has data in the requested period.

The code to reproduce:

import pandas as pd
from erddapy import ERDDAP
# method from https://ioos.github.io/erddapy/ and [https://ioos.github.io/erddapy/02-extras-output.html#](https://ioos.github.io/erddapy/02-extras-output.html)
# setup server connection, this takes no time so does not have to be cached
server = "https://uhslc.soest.hawaii.edu/erddap"
e = ERDDAP(server=server, protocol="tabledap", response="nc") #opendap is way slower than nc/csv/html
e.dataset_id = 'global_hourly_rqds'
# set erddap constraints
e.constraints = {}
e.constraints["uhslc_id="] = 3
e.constraints["time>="] = pd.Timestamp('2018-01-01')
e.constraints["time<="] = pd.Timestamp('2018-02-01')
ds = e.to_xarray()

Additional information
When I change to uhlsc_id=6, I get an error that makes sense since Enewetok does not contain data in the requested period:

HTTPError: Error {
code=404;
message="Not Found: Your query produced no matching results. (nRows = 0)";
}

When I change to uhslc_id=7, there is data retrieved as expected, no error is raised.

Approach
2025-05-01: Emailed UHSLC maintainers to ask if they could check their system, it seems that the actual_range is incorrect.
