Modifying Python's requests module to spoof a ja3 fingerprint

(Since the repo seems to be getting some external attention, I want to clarify that this is experimental and not currently in a working state. Thank you!)

TO-DO LIST

• decoder: parse string version of ja3
• patcher: find and replace usages of ssl module in an imported requests module
• monitor: dump ja3 off network using scapy
  • some inconsistency here? some fields don't seem to match ja3 reported by ja3er
  • not sure how to further debug this, client hello packet data from wireshark matches scapy
• imitate: fake ssl module with customizable ja3
  • dummy C extension with setup.py and portable compiler setup
  • dummy pybind11 + cppimport extension (moved to ctypes)
  • ability to verify fakessl against real ssl module can't inspect pybind11 method signatures yet
  • dummy SSLSocket class
  • customized openssl compile options + linkage against C extension
  • usage of compiled openssl in SSLSocket class
  • ssl.wrap_socket at minimum
  • other ssl functions used by requests/urllib3
• tests using ja3s from common browsers
