location fallback (#263)

see https://github.com/karlicoss/HPI/issues/262

* move home to fallback/via_home.py
* move via_ip to fallback
* add fallback model
* add stub via_ip file
* add fallback_locations for via_ip
* use protocol for locations
* estimate_from helper, via_home estimator, all.py
* via_home: add accuracy, cache history
* add datasources to gpslogger/google_takeout
* tz/via_location.py: update import to fallback
* denylist docs/installation instructions
* tz.via_location: let user customize cachew refresh time
* add via_ip.estimate_location using binary search
* use estimate_location in via_home.get_location
* tests: add gpslogger to location config stub
* tests: install tz related libs in test env
* tz: add regression test for broken windows dates

* vendorize bisect_left from python src
doesnt have a 'key' parameter till python3.10
