Fixes #902

Description

Fix AttributeError when Junos devices return interface type fields as lists instead of strings. Added a new normalization function to unwrap list values during data processing.

Type of change

• Bug fix (non-breaking change which fixes an issue)

New Behavior

Junos interface data is now parsed correctly when the device returns type fields as lists. The new normalization function automatically unwraps single-element lists to their string values.

Contrast to Current Behavior

Previously, the parser threw an AttributeError when processing Junos devices that return interface type fields as lists instead of strings, which occurs with certain Junos firmware versions.

Discussion: Benefits and Drawbacks

• Benefits: Junos devices with inconsistent JSON data structures can now be properly monitored by SuzieQ
• Drawbacks: None
• Backwards-compatible: Yes

Changes to the Documentation

None required.
