Do not throw MsticpyVTNoDataError exception when no data is return from vt_lookup.lookup_iocs - vtlookupv3

[2xyo]

Describe the bug

1. investigate a list of observables
2. enrich this list of observables with vt_lookup.lookup_iocs from vtlookupv3
3. get an exception if an observable is not present on virustotal instead of the result

To Reproduce

import pandas as pd
from msticpy import init_notebook
from msticpy.sectools.vtlookupv3 import VTLookupV3, VTEntityType
from msticpy.common.provider_settings import get_provider_settings

import nest_asyncio
nest_asyncio.apply()

init_notebook(namespace=globals());
vt_key = get_provider_settings("TIProviders")["VirusTotal"].args["AuthKey"]
vt_lookup = VTLookupV3(vt_key)

samples_raw = """018ac8f95d5e14b92011cdbfc8c48056ca4891161ed6bdd268770a5b56bb327f
DONOTEXISTDONOTEXISTDONOTEXIST"""
samples = pd.DataFrame({"target":samples_raw.split(),"target_type":"file"})
vt_lookup.lookup_iocs(observables_df=samples, observable_column="target")

Minimized stacktrace

APIError                                  Traceback (most recent call last)
APIError: ('NotFoundError', 'Resource not found.')
The above exception was the direct cause of the following exception:
MsticpyVTNoDataError                      Traceback (most recent call last)
MsticpyVTNoDataError: An error occurred requesting data from VirusTotal

Expected behavior

A dataframe with 2 rows

1. a first row with the data for 018ac8f95d5e14b92011cdbfc8c48056ca4891161ed6bdd268770a5b56bb327f
2. a second raw with NaN or None value for DONOTEXISTDONOTEXISTDONOTEXIST (or an equivalent to inform the analyst that the observable was not found on VT)

Not finding an observable on VT is fundamentally not an error, it is an event that is potentially expected and this should not prevent retrieving the results for the other observables.

Additional context

msticpy version installed: 1.3.1

Hi @2xyo - this should be fixed in PR #199.
Hopefully will release next week.
