v0.7.0 : Haldex Support, Bugfixes, Remove ESP32 Code

NOTE: The Windows build for this release has file path issues and has been pulled. The code functions correctly, but I need to update to support the latest pyinstaller.

• Removes all native support for A0/ESP32 operations (reflashing a dongle, direct BLE connection, etc.), as there is no longer an open source firmware which supports the protocol VW_Flash was using. Please visit https://github.com/Switchleg1/esp32-isotp-ble-bridge/releases/tag/v0.90 for a VW_Flash, J2534-compatible firmware for A0/ESP32 devices. This firmware is now used over J2534 like any other device - there's no special provision in VW_Flash for it anymore.
• Adds support for Gen 5 MQB Haldex thanks to ConnorHowell. Please do not use this support at this stage unless you are competent in Haldex recovery using a Miniwiggler cable. Haldex modules are easy to brick. You have been warned.
• Fixes some small bugs.
