Added support for Python 3.10

[giswqs]

ee.Initialize() does not work with Python 3.10. Here is a workaround. With this PR, users can continue to use geemap.Map() or geemap.ee_initialize() to initialize ee with Python 3.10.

import ee
import httplib2
ee.Authenticate(auth_mode='notebook')
ee.Initialize(http_transport=httplib2.Http())
