importing uc from seleniumwire ignores proxy option
On newer versions of undetected chromedriver, I need to use this arg ``use_subprocess=True`` else I can't run it without getting a Runtime error. (https://github.com/ultrafunkamsterdam/undetected-chromedriver/issues/432) This argument seems to break the usage of proxies with selenium wire though.

```python
import seleniumwire.undetected_chromedriver.v2 as uc
from seleniumwire import webdriver

chrome_options = webdriver.ChromeOptions()
chrome_options.headless = False
seleniumwire_options = {'proxy': {'https': 'type://host:port',}} 
driver = uc.Chrome(options=chrome_options, seleniumwire_options=seleniumwire_options, use_subprocess=True)

driver.get('https://whatismyipaddress.com/')
```

Ignores passed proxy option and loads website without proxy.
