Improve error handling and email visibility in core.py

[debpramanik]

Issue Fixed

The tool was crashing on certain accounts (e.g., private accounts without IGTV data) due to a KeyError when accessing missing API fields.

Error Example

Informations about     : [username redacted]
userID                 : [userID redacted]
Full Name              : [full name redacted]
Verified               : False | Is buisness Account : False
Is private Account     : True
Follower               : 7 | Following : 12
Number of posts        : 0
Traceback (most recent call last):
  File ".../toutatis/core.py", line 125, in main
    print("IGTV posts             : " + str(infos["total_igtv_videos"]))
                                            ~~~~~^^^^^^^^^^^^^^^^^^^^^
KeyError: 'total_igtv_videos'

Changes Made

1. Fixed KeyError - Used safe dictionary access (.get()) for total_igtv_videos field
2. Enhanced public email reporting - Always indicate presence/absence of public email
3. Enhanced obfuscated email reporting - Always indicate presence/absence of obfuscated email

Benefits

• ✅ Prevents crashes when processing accounts with missing API fields
• ✅ Improves robustness and user experience
• ✅ Provides clearer, more consistent output

Files Changed

• toutatis/core.py

Testing

Verified on multiple Instagram usernames including:

• Private accounts
• Accounts without IGTV content
• Various account types

No crashes observed, and email status is now always reported consistently.
