[Feature Request]: Add ja4
Describe the feature / enhancement and how it would improve things
Has the browser already used ja4 fingerprint verification? Have you considered adding ja4?
Describe how your proposal will work, with code and/or pseudo-code
Add ja4 and ja4 hash to client_test_utils.go
Sample Code showing JA4 failure.:
#!/usr/bin/env python3
