No faked user agent

[jze]

frictionless-py uses a fake user agent:

frictionless-py/frictionless/settings.py

Lines 56 to 62 in be08dcf

	DEFAULT_HTTP_HEADERS = {
	"User-Agent": (
	"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) "
	"AppleWebKit/537.36 (KHTML, like Gecko) "
	"Chrome/54.0.2840.87 Safari/537.36"
	)
	}

That is a typical behavior of malicious bots. Therefore, many bot defense programs will block requests from frictionless-py.
