fix: Fragmented video verification

[timmurphydev]

Changes in this pull request

This PR fixes a couple of issues with validating fragmented video.

The first is that trust cannot be configured via settings because thread_local_settings is not being passed in when creating the context in from_fragmented_files.

The second is that when validating fragmented video, the SDK is always returning a assertion.bmffHash.mismatch error from load_from_file_and_fragments. This is because the from_stream call results in a call to verify_store with the init segment being validated alone like a full video. The mismatch error gets accumulated here. Then if verify is true, the validation will succeed on the second pass with the init segment and fragments, but the error is still present from the first pass. The fix follows the existing pattern in load_fragment_from_stream except that it destructures the result and tests remote_url, even though it is probably always None for fragmented video.
