Hidden / dashboard-only blogs are pretty straightforward and "only"
require a valid 'access-token' and 'access-token-secret' for the given
'api-key' and 'api-secret', so that signed OAuth1.0 requests are possible.
Private / password protected blogs on the other hand are a bit
cumbersome. In addition to a valid 'access-token' and
'access-token-secret', they also require the account belonging to those
tokens to be a member of the blog itself. Knowing the password and
entering it in the website isn't enough to access a blog through the
API. Following a private blog is also impossible, so that option can't
work either.
* [instagram] Add extractor for instagram.com user profiles and pages
The extractor scrapes `instagram.com/<user>' timelines and
`instagram.com/p/<shortcode>' by mimicking the behaviour of a web
browser and extracting the sharedData JSON of the single pages.
Please note that this mean that for user timelines we also do an
extra request to the `instagram.com/p/<shortcode>' page but this
permit to have consistent (and all) information about the media
fetched.
The MD5 logic used for X-Instagram-GIS was documented in

* [instagram] Test for keywords, not url for GraphImage and GraphSidecar
URLs returned by instagram seems not stable so avoid testing for
them and instead test for keyword returned.
* [instagram] Improve test of InstagramProfilepageExtractor
Also check the count of media returned.
* [instagram] Several cleanup and improvements
- Change description, subcategories to generate a better description in
docs/supportedsite.rst
- Remove not needed InstagramExtractor.__init__()
- Use text.parse_int() instead of directly using int() (the former is more
robust)
- Use self.request().json() instead of using json.loads() the
self.request().text()
- Add `pattern:' to check the URLs where we do not have a stable URLs.
It seems that only the subdomain is not stable.
Thanks to @mikf!
While a filename might not be a real 'hash', or comparable to what
tumbler usually provides, it is still better than an empty string.
At least as long as "alternatives" in format strings aren't implemented.
