Google Session Key/Value Format

[madprogramer]

To "simulate" a log-in to a Google account, it's possible to use 3 session keys:

• SID
• SSID
• HSID

The following is my current understanding of the format the values for these come in:

• SID: 70 alphanumeric upper and lower case characters, with dashes in between followed by a final . That's 71 characters in total.
• SSID: 17 alphabetic upper and lower case characters
• HSID: 17 alphanumeric upper and lower case characters, with underscores.

If these are correct, I will update the interactive instructions to describe the shape of the values for these cookies, and later also add in a session-cookie shape checker, to make sure cookies are valid.

Until then, the DoAError exception can be used to validate cookies. A DoAError (Denial of Access Error) is raised when invalid cookie values are used to access a private file.

Partially fixed with #9
SAPISID and APISID are also a thing now, apparently
