Add Google Voice Parsers (User Accounts, Calls, Voicemails, and Messages)

[campwill]

This pull request adds support for parsing user accounts, phone calls, voicemails, and messages from the Google Voice application. The plugin has been tested to work on app version 2025.07.20.788599304 (October 29th, 2025).

Google Voice is an application that allows users to obtain a free, non-fixed Voice over IP (VoIP) phone number. Due to its nature, Google Voice can be used for both legitimate and malicious purposes, allowing users to communicate with others using an assigned VoIP number. The Google Voice application stores communication data that may be relevant in an investigation.

We have conducted extensive documented research of the analysis of Google Voice. A blog on our findings can be found here: https://blogs.dsu.edu/digforce/2025/11/10/taking-off-the-mask-forensic-analysis-of-google-voice/

If you find any compatibility issues, have any suggestions, or need any more information, please let us know.

@campwill if you want the parsers to be part of the timeline feature, make sure to have the timestamp be the first column in any of the reports

I've swapped the Timestamp column to be first in the relevant reports.
