Query builder fails with parameter which are subclasses of str

[mmarseu]

In certain situations, when passing subsclasses of str as parameters, there are not recognized as strings and incorrectly encoded in a query. Specifically, I stumbled over this problem when passing a enum.StrEnum to the office365.sharepoint.lists.collections.ListCollection.get_by_id() method. The resulting error resembles this (note the missing single quotes around the GUID):

office365.runtime.client_request_exception.ClientRequestException: ('-1, Microsoft.SharePoint.Client.InvalidClientQueryException', 'The expression "Lists/GetById(53bef8eb-4048-4303-b939-0e582adc49e2)" is not valid.', '400 Client Error: Bad Request for url: https://<tenand-id>.sharepoint.com/teams/<team_name>/_api/Lists/GetById(53bef8eb-4048-4303-b939-0e582adc49e2)?$select=*')

Here's the callstack at the location where the problem occurs (on v.2.6.2):

is_string_type (office365\runtime\compat.py:41)
_encode_method_value (office365\runtime\paths\builder.py:56)
build_segment (office365\runtime\paths\builder.py:46)

__str__ (office365\runtime\paths\resource_path.py:28)
resource_url (office365\runtime\client_object.py:227)

execute_query (office365\runtime\client_runtime_context.py:173)
execute_query (office365\runtime\client_object.py:55)

The culprit is in line 41 here: https://github.com/vgrem/office365-rest-python-client/blob/8f6ce06751f1a2ce75b620379d3f5b87d6393506/office365/runtime/compat.py#L37-L41

Why not replace this with isinstance(value, str) which would cover subclasses of str such as StrEnum?
