Client get_runs is extremely slow

[wk9874]

Description of Bug

client.get_runs() is very slow, and appears to do a GET to every run in turn

Steps To Reproduce

client = simvue.Client()

_runs = client.get_runs(
filters=["folder.path == /GS2/test_data"],
metrics=True,
count_limit=5000,
output_format='dataframe'
)

_runs.to_csv("output.csv")

This pulls 4000 runs and takes tens of minutes.

Expected behavior

Should be much faster and not doing GETs to each individual endpoint.

Actual Behaviour

Does a GET to each endpoint:

GET to: https://uk.simvue.io/api/version, Params: None
GET to: https://uk.simvue.io/api/runs, Params: {'attributes': 'null', 'filters': '["folder.path == /GS2/test_data"]', 'return_basic': True, 'return_system': False, 'return_timing': False, 'return_metrics': True, 'return_alerts': False, 'return_metadata': False, 'count': 100, 'start': 0}
