Cannot set id constraints in v8

[imranq2]

In v7, we used to use the following code to allow bad ids we get from data sources before we fix them:

from fhir.resources.R4B.fhirtypes import Id


"""
These settings are for fhir.resources package

"""
regex = re.compile(
    r"^[A-Za-z0-9\-_.]+$"
)  # allow _ since some resources in our fhir server have that
# remove the 64-character limit on ids
Id.configure_constraints(min_length=1, max_length=1024 * 1024, regex=regex)

In v8, we get the error:

from fhir.resources.R4B.fhirtypes import Id was not found

What is the way to achieve the same goal in v8?
