Add _field_types attribute to GroupedRecord

[B0TAxy]

When using --hash, --resolve, or both, there's a script called record_modifier.py that tries to find the fields and then performs the requested action, adding a new field afterward. However, since the GroupedRecord class doesn’t have the self._field_types attribute, it just crashes every time a GroupedRecord is involved. This code fixes that issue.

Fixes #168

Thanks! Could you also add a regression test that tests the old broken situation?

Hi,
Thanks for the review. I've added a regression test — please let me know if it's sufficient.

Pull Request Overview

This PR fixes a bug in record_modifier.py where a GroupedRecord instance would crash due to the missing _field_types attribute. The changes include adding an expected field type mapping in the tests and initializing _field_types in the base GroupedRecord constructor.

• Updated tests in tests/test_record.py to verify the _field_types attribute.
• Modified flow/record/base.py to initialize the _field_types attribute based on the RecordDescriptor.

Reviewed Changes

Copilot reviewed 2 out of 2 changed files in this pull request and generated 2 comments.

File	Description
tests/test_record.py	Added new assertions to check the _field_types attribute and expected field mappings; minor spelling errors in variable/comments need correction.
flow/record/base.py	Initializes _field_types to maintain compatibility with RecordDescriptor.

Looks good, thanks for the pointer where it goes wrong. It seems that dissect.target is using a private attribute to get the fields.

Can you apply the above suggestions by copilot? PR looks good otherwise for merge.
